Episode 40 : DESIGN EXAMPLE – DILUTE PHASE PNEUMATIC CONVEYING
DESIGN EXAMPLE – DILUTE PHASE PNEUMATIC CONVEYING
A plastics production plant wants to increase the capacity through an existing conveying system. The existing system has 6 inch ID pipes and is configured as shown in the diagram below.
The High Density Polyethylene (HDPE) particles have an average size of 4 mm. The conveying gas is at 68oF. The existing blower can produce 1375 SCFM.
The desired capacity increase is from 20,000 lbm/hr to 30,000 lbm/hr. Can the existing blower and pipe system meet this increase in capacity?
Assume the pressure drop across the cyclone is 5 inches of water. The pressure drop across the blower inlet pipe and silencers is 0.3 psi. The pipe bends have R/D = 6. Pipe roughness is k = 0.00015 ft. The particles have density pρ = 59 lbm/ft3. Terminal velocity of the particles is = 30.6 ft/s.

Butterfly valves are widely used in hydro power plants to regulate and control the flow
through hydraulic turbines. That’s why it is important to design the valve in such a way that it can give
best performance so that optimum efficiency can be achieved in hydraulic power plants. Conventionally
that the models of large size valves are straight in the laboratory to determine their performance
characteristics. This is a time consuming and costly process. High computing facility along with the use
of numerical techniques can give the solution to any fluid flow problem in a lesser time. In this research
work flow analysis through butterfly valve with aspect ratio 1/3 has been performed using
computational software. For modelling the valve ICEM CFD 12 has been used. Valve characteristics
such as flow coefficient and head loss coefficient has been determined using CFX 12 for different valve
opening angle as 30°,60°,75°, and 90° (taking 90°as full opening of the valve) for incompressible fluid.
Value of head loss coefficient obtained from numerical analysis has been compared with the
experimental results.
This is a preliminary text for the chapter. The Oslo Group is invited to provide comments on the
general structure and coverage of the chapter (for example, if it covers the relevant aspects related to
measurement units and conversion factors, and if there are additional topics that should be covered in
this chapter), and on the recommendations to be contained in IRES.
The current text presents the recommendations from the UN Manual F.29 as well as some points that
were raised during the last OG meeting. The issue of “harmonization” of standard/default conversion
factors still needs to be addressed. It was suggested that tables be moved to an annex. Please provide
your views on which ones should be retained in the chapter.

CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
Quality defects in TMT Bars, Possible causes and Potential Solutions.PrashantGoswami42
Maintaining high-quality standards in the production of TMT bars is crucial for ensuring structural integrity in construction. Addressing common defects through careful monitoring, standardized processes, and advanced technology can significantly improve the quality of TMT bars. Continuous training and adherence to quality control measures will also play a pivotal role in minimizing these defects.

3. Aim of the experiment:-
. Compression between different flow meter types.
. Determining the discharge coefficient.
Introduction:-
Fluid mechanics has developed an analytical discipline from the
application of the classical laws of static, dynamics and
thermodynamics, to situation in which fluids can be treated as
continuous media. The particular laws involved are those of
conservation of mass; these laws may be
simplified in an attempt to describe
quantitatively the behavior of the fluids.
The hydraulic bench service module, F1-
10, provides the necessary facilities to
support a comprehensive range of
hydraulic models each of which is
designed to demonstrate a particular
aspect of hydraulic theory. The specific
hydraulic model that is concerned for this
experiment is the flow meter test rig (F1-
21). This consists of venture meter,
variable area meter, and orifice plate installed in a series of
configurations to allow for direct comparisons.

4. Apparatus:-
The apparatus is discharged to demonstrate three basics
types of flow meter.
-Rota meter
Rota meter:-
A Rota meter with the following characteristics is used to measure
flow rate:
- Plastic measuring tub
5. - Interchangeable stainless steel float
- Max. Flow rate 26 lit/min
The flow rate can be read from the upper edge of the conical
attachment.
Air particles on dirt particles on the float may affect measurement
precision.

To do so, open all cocks fully.
Nozzle and Orifice plate:
The orifice plate housing is made of transparent plastic allowing
visible functioning of the orifice plate. The flow causes a pressure
loss between inlet and outlet. Two tapings allow measurement of
inlet and outlet pressure. This differential pressure (p1-p2) is
proportional to the volume flow rate:

13. standard nozzle which enlarges an exact working fluid maintained
at the similar initial conditions and pressures.
It has no dimensions and depends directly on the rate of flow and
velocity of working fluid. It is symbolized by Cd and its value is
different for each fluid depending on the kind of measurement of
flow. In nozzle flow measurement, the efficiency of Cd is higher
when compared to the flow measurement at the orifice. The
discharge coefficient is raised by increasing the overall pressure
ratio and reducing the convergence semi angle. Also, the range of
Cd is commonly superior in supercritical series.
Express the relation of discharge coefficient.
