This presentation will provide knowledge on different types of water pump. Working mechanism of each pump is described effectively with advantages and disadvantages of each.
Centrifugal pumps work by using an impeller to increase the pressure and flow of a liquid. Liquid enters the center of the impeller and is accelerated outward by the curved blades of the impeller. This increases the pressure and flow of the liquid. Calculating the required head of a centrifugal pump involves accounting for static head, pipe friction losses, and adding additional head for safety. Proper pump selection is based on matching the required head and flow rate to the pump performance curves. Cavitation and ensuring adequate Net Positive Suction Head (NPSH) are also important considerations for centrifugal pump operation.

An electrical submersible pump (ESP) is used to increase the pressure of well fluid and push it to the surface from deeper wells. It consists of a subsurface electric motor, seal section to connect the motor to multiple centrifugal pump stages, and an electric cable. The motor turns at high rpm to power the pump stages, each with an impeller and diffuser, to boost the fluid pressure stage by stage until it reaches the surface. ESPs provide high production volumes but require high voltages and more maintenance due to wear from sand and fluids. They are advantageous for deep wells but can have issues with sand and require careful installation and operation.

Embedded machine learning-based road conditions and driving behavior monitoringIJECEIAES
Car accident rates have increased in recent years, resulting in losses in human lives, properties, and other financial costs. An embedded machine learning-based system is developed to address this critical issue. The system can monitor road conditions, detect driving patterns, and identify aggressive driving behaviors. The system is based on neural networks trained on a comprehensive dataset of driving events, driving styles, and road conditions. The system effectively detects potential risks and helps mitigate the frequency and impact of accidents. The primary goal is to ensure the safety of drivers and vehicles. Collecting data involved gathering information on three key road events: normal street and normal drive, speed bumps, circular yellow speed bumps, and three aggressive driving actions: sudden start, sudden stop, and sudden entry. The gathered data is processed and analyzed using a machine learning system designed for limited power and memory devices. The developed system resulted in 91.9% accuracy, 93.6% precision, and 92% recall. The achieved inference time on an Arduino Nano 33 BLE Sense with a 32-bit CPU running at 64 MHz is 34 ms and requires 2.6 kB peak RAM and 139.9 kB program flash memory, making it suitable for resource-constrained embedded systems.

Using data from 41 years in Patna’ India’ the study’s goal is to analyze the trends of how often it rains on a weekly, seasonal, and annual basis (1981−2020). First, utilizing the intensity-duration-frequency (IDF) curve and the relationship by statistically analyzing rainfall’ the historical rainfall data set for Patna’ India’ during a 41 year period (1981−2020), was evaluated for its quality. Changes in the hydrologic cycle as a result of increased greenhouse gas emissions are expected to induce variations in the intensity, length, and frequency of precipitation events. One strategy to lessen vulnerability is to quantify probable changes and adapt to them. Techniques such as log-normal, normal, and Gumbel are used (EV-I). Distributions were created with durations of 1, 2, 3, 6, and 24 h and return times of 2, 5, 10, 25, and 100 years. There were also mathematical correlations discovered between rainfall and recurrence interval.
Findings: Based on findings, the Gumbel approach produced the highest intensity values, whereas the other approaches produced values that were close to each other. The data indicates that 461.9 mm of rain fell during the monsoon season’s 301st week. However, it was found that the 29th week had the greatest average rainfall, 92.6 mm. With 952.6 mm on average, the monsoon season saw the highest rainfall. Calculations revealed that the yearly rainfall averaged 1171.1 mm. Using Weibull’s method, the study was subsequently expanded to examine rainfall distribution at different recurrence intervals of 2, 5, 10, and 25 years. Rainfall and recurrence interval mathematical correlations were also developed. Further regression analysis revealed that short wave irrigation, wind direction, wind speed, pressure, relative humidity, and temperature all had a substantial influence on rainfall.
Originality and value: The results of the rainfall IDF curves can provide useful information to policymakers in making appropriate decisions in managing and minimizing floods in the study area.
DEEP LEARNING FOR SMART GRID INTRUSION DETECTION: A HYBRID CNN-LSTM-BASED MODELijaia
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%.

Electric vehicle and photovoltaic advanced roles in enhancing the financial p...IJECEIAES
Climate change's impact on the planet forced the United Nations and governments to promote green energies and electric transportation. The deployments of photovoltaic (PV) and electric vehicle (EV) systems gained stronger momentum due to their numerous advantages over fossil fuel types. The advantages go beyond sustainability to reach financial support and stability. The work in this paper introduces the hybrid system between PV and EV to support industrial and commercial plants. This paper covers the theoretical framework of the proposed hybrid system including the required equation to complete the cost analysis when PV and EV are present. In addition, the proposed design diagram which sets the priorities and requirements of the system is presented. The proposed approach allows setup to advance their power stability, especially during power outages. The presented information supports researchers and plant owners to complete the necessary analysis while promoting the deployment of clean energy. The result of a case study that represents a dairy milk farmer supports the theoretical works and highlights its advanced benefits to existing plants. The short return on investment of the proposed approach supports the paper's novelty approach for the sustainable electrical system. In addition, the proposed system allows for an isolated power setup without the need for a transmission line which enhances the safety of the electrical network

Gas agency management system project report.pdfKamal Acharya
The project entitled "Gas Agency" is done to make the manual process easier by making it a computerized system for billing and maintaining stock. The Gas Agencies get the order request through phone calls or by personal from their customers and deliver the gas cylinders to their address based on their demand and previous delivery date. This process is made computerized and the customer's name, address and stock details are stored in a database. Based on this the billing for a customer is made simple and easier, since a customer order for gas can be accepted only after completing a certain period from the previous delivery. This can be calculated and billed easily through this. There are two types of delivery like domestic purpose use delivery and commercial purpose use delivery. The bill rate and capacity differs for both. This can be easily maintained and charged accordingly.
6. How it works
1. Each combination of a
chamber with an impeller
is referred to as a “stage”
or “bowl”
2. Each stage adds lift to the
pump
3. The impellers are directly
connected to the motor
which creates flow.
4. As with all variable
displacement pumps:
flow rate is inversely
related to the head
pressure.
7. Pump Parameters
Q: So what determines the necessary size of the pump?
A: Flow rate & the amount of lift required.
1. Flow Rate: Make sure the aquifer is capable of
supporting your desired flow rate. Do you have any
pump test data? Why not?
2. Lift: Submersible pumps do not build pressure. They
provide lift which overcomes head pressure, which is
measured in feet.
The head pressure against which a submersible pump
operates is referred to as…
TOTAL DYNAMIC HEAD (TDH)

9. Friction Loss
Q: How do I quantify friction loss?
Friction Loss is a result of water’s resistance to flow.
It’s affected by…
• Flow Rate
• Pipe diameter and type
• Number and type of fittings and valves
A: Darcy-Weisbach equation:
Hf = ∆p/γ = f (L/D)x(V/2g)
Or you can just look it up!

14. Worksheet:
Peter Piper picked a peck
of pickled pumps!
How to size a pump:
1. What is required/desired flow (GPM)
2. Determine TDH
3. Consult Pump Curve(s)
4. Select wire size
15. How to size a pump:
What is required/desired flow? 5 GPM
Determine TDH
First, let’s calculate friction loss!
Friction loss = total length X friction loss (straight pipe) factor + friction loss (fittings)
Friction loss = (_____’ X _____’/_____’) + (__’ X __)
Friction loss = _____’ + _____’
Friction loss = _____’ Head Pressure
Now we can calculate TDH!
TDH = pumping level + vertical rise + friction loss
TDH = _____’ + _____’ + _____’
TDH = _____’
Now that we know the TDH and required/desired flow, we can select a pump from a performance
curve.
Which 4” pump/motor combination will deliver 5 GPM at the calculated TDH?

19. How to size a pump:
What is required/desired flow? 5 GPM
Determine TDH
First, let’s calculate friction loss!
Friction loss = total length X friction loss (straight pipe) factor + friction loss (fittings)
Friction loss = ( 922 ’ X 1.8 ’/ 100 ’) + ( 3 ’ X 2 ) (1.8’/100’)
Friction loss = 16.60 ’ + .108 ’
Friction loss = 17 ’ Head Pressure
Now we can calculate TDH!
TDH = pumping level + vertical rise + friction loss
TDH = 500 ’ + 222 ’ + 17 ’
TDH = 739 ’
Now that we know the TDH and required/desired flow, we can select a pump from a performance
curve.

5S20-39DS (2 HP) .
22. Power Requirements
Q: I’ve selected my pump. Am I done yet?
A: Not quite. Your pump needs electricity to work.
If there’s no power on site, you need to spec a generator:
• Most submersible pumps with 5HP or less are
230V/single phase. You’ll need 1.5kW per motor HP
So…a 5HP pump needs a minimum of 7.5kW
You also need to spec the right power cable
• PVC flat-jacketed wire is the most common. It typically
comes in 500’ rolls, but can be custom ordered to
length.
• The gauge of the wire is a function of your operating
voltage and length.
23. Maintenance & Repair
Q: It’s been two years and the bowls are worn out on my
submersible pump. What do I do?
A: Go back in time and design a better well screen and
filter pack.
A: Okay, you’ll have to pull the pump. Go ahead and hire
someone with a well service rig. DON’T TRY IT YOURSELF!
• Well professionals have the right kind of equipment to
pull a submersible pump without damaging the drop
pipe, power cable and pump itself.
• You don’t.
24. Maintenance & Repair
Q: My pump just stopped working.
What happened?
A: A lot of things could be the
problem, but a common issue is
motor burn-out.
• If water doesn’t flow around
the motor housing on its way
to the intake, the motor isn’t
being cooled properly. This
can lead to overheating.
• Set your pump above your
screen interval but below your
dynamic pumping level so
water comes from below.
• If conditions preclude this
design, consider a shroud.
