Dead weight for Calibration Pressure Gauges Experiment No. (2).pdf

The document describes an experiment to calibrate a Bourdon pressure gauge using a dead weight tester. The experiment involved checking the zero point of the gauge, applying known weights to the tester to increase pressure, and recording the pressure readings from the gauge. Calculations were shown to determine the actual pressure applied based on the mass and area. A calibration curve was plotted comparing the measured pressure to the actual pressure. The results showed the gauge readings were close to the actual pressures, with small errors. Calibrating pressure gauges ensures accurate measurements and the experiment demonstrated how to establish the relationship between readings and actual pressures.

Errors and uncertainities net

- Random uncertainties arise from imprecision in measurements and can cause readings to be above or below the true value. They can be reduced by more precise instruments or repeating measurements.
- Systematic uncertainties result in all readings being consistently too high or too low. They may be due to instrumentation errors or experimental technique and can sometimes be addressed through calibration.
- Uncertainty is incorporated into measurements as a range rather than a single value, and it is important to propagate uncertainties through calculations.

1291 report format and example

- The objective was to test if the relationship between water height and volume in a soda bottle follows a linear relationship, which could then be used to calculate the bottle's circumference.
- Data was collected by measuring the height and volume of water added in 250mL increments. This data fit a linear relationship, allowing the cross-sectional area and circumference to be calculated.
- The calculated circumference did not agree with a direct measurement within uncertainty, suggesting an unaccounted for systematic error such as inaccurately measuring the added water volumes.

Dead – Weight piston gauge & Center of Pressure

The calibration of the Bourdon gauge is the aim of the dead weight pressure gauge experiment, while the center of pressure is the other test’s aim to find the resultant force (F) and center of pressure (hp). For testing and changing pressure gages, the death-weight pressures gage is used. The pressure is exerted by weights which are supported by weight. The latter has a piston that operates on hydraulic oil in the pipe system to show those pressures by a pressure gage that is also attached to the system. A Bourdon gage with a clear dial is included in the device. Thus, there is a simple identification of the display mechanism and the different adaptation choices.

Teoriadelerror21

This document discusses error in measurement and how to calculate absolute and relative error. It explains that there are two types of errors - systematic errors due to the measuring instrument and random errors due to the person taking the measurement. To reduce random errors, multiple measurements are taken and the average is used. The absolute error is defined as the difference between the true value and measured value, while relative error is absolute error divided by the measurement. Examples are provided to demonstrate calculating error through addition, multiplication, and powers when indirect measurements are involved.

A pelton wheel is considered as an impulse turbine, a turbine that converts pressure head into velocity head. This lab will use this mechanism along with a prony brake to calculate the input power, output power, and efficiency of the turbine. The team will be provided with measuring devices such as a stroboscope to measure the turbine speed as well as a hydraulic bench to control the flow rate of the liquid flowing through the turbine [1].
The experiment will consist of two separate trials with two different water heads. This experiment will neglect all frictional forces for the theoretical calculations. The hydraulic bench will be calibrated to have a water head of 8m H2O and 12m H2O. The team will record the needed data for the experiment: turbine inlet pressure, flow rate, turbine speed, and the net spring forces. For the first trial, 8m H2O, the Prony brake net spring force will be set to have a net force of 10N and will be adjusted to decrease by 1N until the net force reaches 4N, having 7 data points for the first trial. The experiment will then be repeated for a water head of 12m H2O with the Prony brake net force set to 12N and adjusted to decrease by 2N until the net force reaches 2N, having 6 data points. The volume of the flow will be recorded at every other data point to ensure that flow rate remains constant.
The team concluded that the efficiency of the turbine increases as the angular velocity increases. The percent error between experimental and theoretical calculations were relatively high. Which were expected because the theoretical calculations did not account for any frictional losses.
INTRODUCTION

Specific Gravity & Absorption of Aggregate (Coarse & Fine) | Jameel Academy

This document reports on a test to determine the specific gravity and absorption of fine and coarse aggregates. The specific gravities of coarse aggregate were found to be 2.55, 2.7, and 2.8 for bulk dry, SSD, and apparent respectively. For fine aggregate, the specific gravities were 2.64, 2.7, and 2.8. The absorptions were 2.3% for coarse and 1.78% for fine. While the specific gravities were normal, the absorptions were outside standard ranges, likely due to errors in measuring the fine aggregate's slump or not waiting 24 hours for coarse aggregate heating. In conclusion, the aggregates tested would not be suitable for use due to

Soundness of Hydraulic Cement Paste | Jameel Academy

This report summarizes the results of a test conducted to determine the soundness of a hydraulic cement paste. The Le-Chatelier test and ASTM C 151-05 autoclave test were performed according to standard procedures. For the Le-Chatelier test, the initial and final distances between indicator points were 7mm and 11mm respectively, resulting in an expansion of 4mm. Since the measured expansion was less than the maximum standard of 10mm, the cement paste was determined to have sufficient soundness for construction applications without risk of cracking. In conclusion, the purpose of the soundness test is to evaluate a cement's ability to retain volume after setting and hardening without excessive expansion that could cause structural issues.

Sieve Analysis of Fine & Coarse Aggregate | Jameel Academy

This report summarizes the results of a sieve analysis test performed on samples of fine and coarse aggregates. Sieve analysis was used to determine the particle size distribution of each aggregate by separating particles via sieves with decreasing size openings. For the fine aggregate, the average size was found to be 0.6mm. For the coarse aggregate, the maximum size was found to be 13.2mm. While the calculations and procedures appeared to be performed correctly, the results did not fully meet specification limits, indicating the aggregates may not be suitable for the intended construction purpose without further processing or testing.

Accident detection system project report.pdf

The Rapid growth of technology and infrastructure has made our lives easier. The
advent of technology has also increased the traffic hazards and the road accidents take place
frequently which causes huge loss of life and property because of the poor emergency facilities.
Many lives could have been saved if emergency service could get accident information and
reach in time. Our project will provide an optimum solution to this draw back. A piezo electric
sensor can be used as a crash or rollover detector of the vehicle during and after a crash. With
signals from a piezo electric sensor, a severe accident can be recognized. According to this
project when a vehicle meets with an accident immediately piezo electric sensor will detect the
signal or if a car rolls over. Then with the help of GSM module and GPS module, the location
will be sent to the emergency contact. Then after conforming the location necessary action will
be taken. If the person meets with a small accident or if there is no serious threat to anyone’s
life, then the alert message can be terminated by the driver by a switch provided in order to
avoid wasting the valuable time of the medical rescue team.

DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODEL

As digital technology becomes more deeply embedded in power systems, protecting the communication
networks of Smart Grids (SG) has emerged as a critical concern. Distributed Network Protocol 3 (DNP3)
represents a multi-tiered application layer protocol extensively utilized in Supervisory Control and Data
Acquisition (SCADA)-based smart grids to facilitate real-time data gathering and control functionalities.
Robust Intrusion Detection Systems (IDS) are necessary for early threat detection and mitigation because
of the interconnection of these networks, which makes them vulnerable to a variety of cyberattacks. To
solve this issue, this paper develops a hybrid Deep Learning (DL) model specifically designed for intrusion
detection in smart grids. The proposed approach is a combination of the Convolutional Neural Network
(CNN) and the Long-Short-Term Memory algorithms (LSTM). We employed a recent intrusion detection
dataset (DNP3), which focuses on unauthorized commands and Denial of Service (DoS) cyberattacks, to
train and test our model. The results of our experiments show that our CNN-LSTM method is much better
at finding smart grid intrusions than other deep learning algorithms used for classification. In addition,
our proposed approach improves accuracy, precision, recall, and F1 score, achieving a high detection
accuracy rate of 99.50%.

A high-Speed Communication System is based on the Design of a Bi-NoC Router, ...

The Network on Chip (NoC) has emerged as an effective
solution for intercommunication infrastructure within System on
Chip (SoC) designs, overcoming the limitations of traditional
methods that face significant bottlenecks. However, the complexity
of NoC design presents numerous challenges related to
performance metrics such as scalability, latency, power
consumption, and signal integrity. This project addresses the
issues within the router's memory unit and proposes an enhanced
memory structure. To achieve efficient data transfer, FIFO buffers
are implemented in distributed RAM and virtual channels for
FPGA-based NoC. The project introduces advanced FIFO-based
memory units within the NoC router, assessing their performance
in a Bi-directional NoC (Bi-NoC) configuration. The primary
objective is to reduce the router's workload while enhancing the
FIFO internal structure. To further improve data transfer speed,
a Bi-NoC with a self-configurable intercommunication channel is
suggested. Simulation and synthesis results demonstrate
guaranteed throughput, predictable latency, and equitable
network access, showing significant improvement over previous
designs

Prediction of Electrical Energy Efficiency Using Information on Consumer's Ac...

Energy efficiency has been important since the latter part of the last century. The main object of this survey is to determine the energy efficiency knowledge among consumers. Two separate districts in Bangladesh are selected to conduct the survey on households and showrooms about the energy and seller also. The survey uses the data to find some regression equations from which it is easy to predict energy efficiency knowledge. The data is analyzed and calculated based on five important criteria. The initial target was to find some factors that help predict a person's energy efficiency knowledge. From the survey, it is found that the energy efficiency awareness among the people of our country is very low. Relationships between household energy use behaviors are estimated using a unique dataset of about 40 households and 20 showrooms in Bangladesh's Chapainawabganj and Bagerhat districts. Knowledge of energy consumption and energy efficiency technology options is found to be associated with household use of energy conservation practices. Household characteristics also influence household energy use behavior. Younger household cohorts are more likely to adopt energy-efficient technologies and energy conservation practices and place primary importance on energy saving for environmental reasons. Education also influences attitudes toward energy conservation in Bangladesh. Low-education households indicate they primarily save electricity for the environment while high-education households indicate they are motivated by environmental concerns.

- 1. University of Duhok College of Engineering Civil Department Fluid Mechanics – Practical Fluid Laboratory A Report About : Center of Pressure on Vertical Fully Submerged Plate Student Name : Jameel Masoud Jameel Class : B Date of Experimental : 23 / 11 / 2017 Date of Submitting : 10 / 12 / 2017 Experiment No. : 3
- 2. Procedure : 1) Moment of inertia, area of torroid and the distance from pivot to the balance pan must be noted if not given. Check the straight of apparatus and Don’t vibrate the apparatus during procedure. 2) Add water into the center of pressure's apparatus until submerge all plate to the water. 3) Place weight to the balance pan and then fill out water by opening drain cock until the beam level indicator stop in the middle which is make a balance between water, weight in balance pan and adjustable counterbalance. 4) Measure the distance from end face of torroid to the water surface using the ruler (scale) that shown in the torroid. 5) Reaped the procedure. But just change the weight (decrease it) and add water until the beam level indicator stop at middle and measure the distance from end face of torroid to the water surface again .
- 3. Calculations and Results : We will calculate the Center of pressure by using this formula : ( hp )actual = y – d2 ( hp )theory = h́ + IG Ah́ Where : y = ML Ah́ , d2 = 20 – d1 , h́ =d1 – 5 Errors % = ( hp )theory− ( hp )actual ( hp )theory × 100 Note : A=75 cm2 , L=27.5 cm , IG = 625 cm4 For example : Mass = 450 gm , d1 = 15.35 cm h́ = d1 − 5 = 15.35 − 5 = 𝟏𝟎. 𝟑𝟓 𝐜𝐦 y = ML Ah́ = 450 × 27.5 75 × 10.35 = 𝟏𝟓. 𝟗𝟒 𝐜𝐦 d2 = 20 − d1 = 20 − 15.35 = 4.65 𝐜𝐦 Center of pressure will be : ( hp )actual = y − d2 = 15.94 − 4.65 = 𝟏𝟏. 𝟐𝟗 𝐜𝐦 ( hp )theory = h́ + IG Ah́ = 10.35 + 625 75 × 10.35 = 𝟏𝟏. 𝟏𝟓𝟓 𝐜𝐦 The error between the actual pressure's center and theory in (%) is : Errors % = ( hp )theory − ( hp )actual ( hp )theory × 100 = 11.155− 11.155 × 100 = −1.21% - The minus sign in errors indicate that actual pressure center is greater than theory pressure center.
- 4. Detail's Table : No. Mass (gm) d1 (cm) h́ (cm) Y (cm) d2 (cm) ( hp )actual (cm) ( hp )theory (cm) Errors % 1 450 15.35 10.35 15.94203 4.65 11.29203 11.15515 1.21 2 410 14.35 9.35 16.07843 5.65 10.42843 10.24127 1.79 3 370 13.4 8.4 16.15079 6.6 9.550794 9.392063 1.66 4 350 12.9 7.9 16.24473 7.1 9.144726 8.954852 2.08 5 300 11.65 6.65 16.54135 8.35 8.191353 7.903133 3.52 6 250 10.4 5.4 16.97531 9.6 7.375309 6.94321 5.86 The relationship between the actual pressure's center and theory is : 6 6.5 7 7.5 8 8.5 9 9.5 10 10.5 11 11.5 12 6 6.5 7 7.5 8 8.5 9 9.5 10 10.5 11 11.5 (hp)theory ( hp )actual Relationship between (hp)actual and ( hp )theory
- 5. Discussion and Conclusion : In this test we determine the Center of pressure on vertical fully submerged plate, and finally we got a result after doing all procedure accuracy, which is different pressure's center with different weight. as shown in result, with increasing weight the distance form center of pressure to surface of water will increase and the force in the center of pressure will be increase. in this test we calculate the center of pressure by two methods which is actual and theory, the difference between it, is the errors in actual measurement. we have some errors but it doesn’t mean that our test is wrong, because every test has some errors. in our test the maximum error in percentage is (5.86 %) which is smaller than 10%. the result will approximately or nearly to the right value which is theory pressure's center, therefore from determining errors we can say our test is correct. we know that if we do many tests we will get the right average and the result will be very accuracy. In conclusion the purpose of this test is to determine the actual center of pressure, compare it with theory of pressure's center, the errors that we have in actual pressure's center and how we can calculate the center of pressure in actual. finally, we will get and determine the center of pressure and errors, to know our test was correct or not.
