Sieve analysis and sedimentation analysis are methods used to determine the particle size distribution of soils. Sieve analysis is used to separate coarse particles using sieves of specific sizes, while sedimentation analysis uses the principle that particle settling velocity depends on size to determine the distribution of fine particles using equipment like an Andreasen pipette. Both provide important information about soil composition through measuring the percentages of different particle sizes.

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.

Hierarchical Digital Twin of a Naval Power SystemKerry Sado
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

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.

2. Sieve Analysis
This test is performed to determine The
percentage of different grain sizes contained
within a soil
Is performed to determine the distribution of a
coarse ,large-sized particles, and the
hydrometer method is used to determine the
distribution of the fine particles.
PURPOSE
9. ➔ Sedimentation is a method of
separating entities based on their
particle size
➔ It’s the process where a solid
material gets deposited from a
state of suspension or solution, in
a fluid.
Sedimentation
analysis
10. ➔ Sedimentation method is used for particle sizes
ranging from 1 micrometer to 200 micrometers.
➔ There are 3 commonly used methods:
1. Andreasen pipette
2. Balance
3. Hydrometer
➔ All these methods depend on the idea that the
terminal velocity of a particle in fluid is directly
proportional to its size.
Methods
11. ● The Andreasen apparatus consists of a 200 mm graduated
cylinder which can hold up to 500ml of suspension fluid.
● A pipette is located at the center of the cylinder and its held in
position by a ground glass stopper so that its tip coincides with
the zero level.
● A three way tap allows fluid to be drawn into a 10ml reservoir
which can then be emptied into a beaker of centrifuge tube.
12. ● Allow a homogenous suspension to settle in a cylinder, take
samples from the settling suspension at a fixed horizontal level
over intervals of time.
● Each sample will contain a representative sample of the
suspension, all of which have settled below the level of the
sampling point.
● The concentration of solid in a sample is taken at a time t.
● This concentration is expressed as a percentage of the initial
concentration, gives us the percentage of particles whose falling
velocity are equal to or less than x/t. Substitution in the equation
below gives us the corresponding stokes' diameter.
Procedure
13. Stoke’s diameter is defined as the diameter of the
sphere that would settle at the same rate as the
particle
14. ● The equipment required are simple to use and
inexpensive.
● You can measure a wide range of sizes with
accuracy and the results can be reproduced,
increasing it’s reliability.
Advantages &
Disadvantages
15. ● Sedimentation analyses must be carried out at concentrations
which are low enough for interactive effects between particles
to be negligible. This is so that the terminal velocities can be
assumed to be equal to those of the isolated particles.
● Careful temperature control is necessary to suppress
convection currents
● Large particles create turbulence, causing them to slow down
and get recorded as undersized.
● Particles have to be completely insoluble in the suspending
liquid.

Disadvantages
