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.

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.
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.

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.

2. INTRODUCTION
The thickness of the cylinder is large compared to that of thin cylinder.
i. e., in case of thick cylinders, the metal thickness ‘t’ is more than ‘d/20’,
where ‘d’ is the internal diameter of the cylinder.
Magnitude of radial stress (pr) is large and hence it cannot be neglected. The
circumferential stress is also not uniform across the cylinder wall. The radial
stress is compressive in nature and circumferential and longitudinal stresses are
tensile in nature. Radial stress and circumferential stresses are computed by
using ‘Lame’s equations’.
DJ996
3. LAME’S EQUATIONS (Theory) :
1. Plane sections of the cylinder normal to its axis remain plane and normal even under
pressure.
2. Longitudinal stress (σL) and longitudinal strain (εL) remain constant throughout the
thickness of the wall.
3. Since longitudinal stress (σL) and longitudinal strain (εL) are constant, it follows that
the difference in the magnitude of hoop stress and radial stress (pr) at any point on
the cylinder wall is a constant.
4. The material is homogeneous, isotropic and obeys Hooke’s law. (The stresses are
within proportionality limit).
ASSUMPTIONS:
DJ996
4. LAME’S EQUATIONS FOR RADIAL PRESSURE AND
CIRCUMFERENTIAL STRESS
Consider a thick cylinder of external radius r1 and internal radius
r2, containing a fluid under pressure ‘p’ as shown in the fig. Let ‘L’ be the
length of the cylinder.

5. Consider an elemental ring of radius ‘r’ and thickness ‘δr’ as shown
in the above figures. Let pr and (pr+ δpr) be the intensities of radial
pressures at inner and outer faces of the ring.

6. Consider the longitudinal section
XX of the ring as shown in the
fig.
The bursting force is evaluated
by considering the projected
area, ‘2×r×L’ for the inner face
and ‘2×(r+δr)×L’ for the outer
face .
The net bursting force, P = pr×2×r×L - (pr+δpr)×2×(r+δr)×L
=( -pr× δr - r×δpr - δpr × δr) 2L
Bursting force is resisted by the hoop tensile force developing at the
level of the strip i.e.,
Fr=σc×2 ×δr×L

7. Thus, for equilibrium, P = Fr
(-pr× δr - r×δpr- δpr × δr) 2L = σ c×2×δr×L
-pr× δr - r×δpr- δpr × δr = σ c×δr
Neglecting products of small quantities, (i.e., δpr × δr)
σ c = - pr – (r × δpr )/ δr ...…………….(1)
Longitudinal strain is constant. Hence we have,
since σL, E and μ are constants (σc – Pr) should be constant . Let it be equal to 2a.

10. ANALYSIS FOR LONGITUDINAL STRESS
Consider a transverse section near the end wall as shown in the fig.

11. 1. Variations of Hoop stress and Radial stress are parabolic across the cylinder
wall.
2. At the inner edge, the stresses are maximum.
3. The value of ‘Permissible or Maximum Hoop Stress’ is to be considered on the
inner edge.
4. The maximum shear stress (σ max) and Hoop, Longitudinal and radial strains
(εc, εL, εr) are calculated as in thin cylinder but separately for inner and outer
edges.
