Sachpazis:Terzaghi Bearing Capacity Estimation in simple terms with Calculati...Dr.Costas Sachpazis
Terzaghi's soil bearing capacity theory, developed by Karl Terzaghi, is a fundamental principle in geotechnical engineering used to determine the bearing capacity of shallow foundations. This theory provides a method to calculate the ultimate bearing capacity of soil, which is the maximum load per unit area that the soil can support without undergoing shear failure. The Calculation HTML Code included.

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.

Water scarcity is the lack of fresh water resources to meet the standard water demand. There are two type of water scarcity. One is physical. The other is economic water scarcity.
Hybrid optimization of pumped hydro system and solar- Engr. Abdul-Azeez.pdffxintegritypublishin
Advancements in technology unveil a myriad of electrical and electronic breakthroughs geared towards efficiently harnessing limited resources to meet human energy demands. The optimization of hybrid solar PV panels and pumped hydro energy supply systems plays a pivotal role in utilizing natural resources effectively. This initiative not only benefits humanity but also fosters environmental sustainability. The study investigated the design optimization of these hybrid systems, focusing on understanding solar radiation patterns, identifying geographical influences on solar radiation, formulating a mathematical model for system optimization, and determining the optimal configuration of PV panels and pumped hydro storage. Through a comparative analysis approach and eight weeks of data collection, the study addressed key research questions related to solar radiation patterns and optimal system design. The findings highlighted regions with heightened solar radiation levels, showcasing substantial potential for power generation and emphasizing the system's efficiency. Optimizing system design significantly boosted power generation, promoted renewable energy utilization, and enhanced energy storage capacity. The study underscored the benefits of optimizing hybrid solar PV panels and pumped hydro energy supply systems for sustainable energy usage. Optimizing the design of solar PV panels and pumped hydro energy supply systems as examined across diverse climatic conditions in a developing country, not only enhances power generation but also improves the integration of renewable energy sources and boosts energy storage capacities, particularly beneficial for less economically prosperous regions. Additionally, the study provides valuable insights for advancing energy research in economically viable areas. Recommendations included conducting site-specific assessments, utilizing advanced modeling tools, implementing regular maintenance protocols, and enhancing communication among system components.
2. CONTEXT
• Introduction to cylindrical grinding
• Types of operations
1.Traverse grinding
2.Plunge grinding
• Types of cylindrical grinding machine
1.Plain centre type cylindrical grinding machine
2.Centre type universal grinder
2
3. CYLINDRICAL GRINDING
• The principle of cylindrical grinder is that
the work piece is held between the centers.
It is rotated by a dog and a face plate and
the rotating grinding wheel is feed against
it.
External grinding machine
3
6. TYPES OF OPERATIONS
Two types of operations are carried out
1.Traverse grinding
2.Plunge grinding
Work piece type
Cylindrical surfaces may be straight, curved.
6
7. TRAVERSE GRINDING
This method is used when the job length is more than work piece is lesser than
the width the grinding wheel. The wheel is made to rotate in a fixed position. The
rotating work made to traverse. The grinding is done by giving longitudinal feed to the
grinding wheel.
7
8. PLUNGE GRINDING
This method is used when the length of the work piece is lesser than the width
of the grinding wheel. The grinding is done by giving only cross feed to the grinding
wheel. This is known as plunge grinding.
8
9. TYPES OF CYLINDRICAL GRINDING MACHINE
This machine is used to produce external cylindrical surface. The surfaces
may be straight, tapered, steps or profiled. Broadly there are two different types of
cylindrical grinding machine as follows:
1.Plain centre type cylindrical grinder
2.Centre type universal grinder
9
10. PLAIN CENTRE TYPE CYLINDRICAL GRINDER
The machine is similar to a centre lathe in many respects. The
workpiece is held between head stock and tailstock centres. A disc type
grinding wheel performs the grinding action with its peripheral surface. Both
traverse and plunge grinding can be carried out in this machine.
The grinding machine consists of various parts
1.Base
2.Table
3.Head stock
4.Tail stock
5.Wheel head
10
12. CENTRE TYPE UNIVERSAL GRINDER
Centre type universal grinders are widely used in tool room for grinding tools.
12
13. The features of this machine are similar to those of plain grinders but it
addition, it is provided with the following features.
1.The centre of the head stock spindle can be used as alive or dead. The work can be
held and revolved by a chuck.
2.The wheel head can be swiveled in a horizontal plane in any angle and it can be fed
in the inclined direction also.
3.The headstock can be swiveled to any angle in the horizontal plane.
4.The wheel head can also be arranged for internal grinding.
