Once the friction factors of the pipes are obtained (or calculated from pipe friction laws such as the Darcy-Weisbach equation), we can consider how to calculate the flow rates and head losses on the network. Generally the head losses (potential differences) at each node are neglected, and a solution is sought for the steady-state flows on the ...
The first nine blocks in the solution to the single-wide block-stacking problem with the overhangs indicated. In statics, the block-stacking problem (sometimes known as The Leaning Tower of Lire (Johnson 1955), also the book-stacking problem, or a number of other similar terms) is a puzzle concerning the stacking of blocks at the edge of a table.
The half-space approach is an elegant solution strategy for so-called "smooth-edged" or "concentrated" contact problems. If a massive elastic body is loaded on a small section of its surface, then the elastic stresses attenuate proportional to 1 / d i s t a n c e 2 {\displaystyle 1/distance^{2}} and the elastic displacements by 1 / d i s t a n ...
Serghides's solution is used to solve directly for the Darcy–Weisbach friction factor f for a full-flowing circular pipe. It is an approximation of the implicit Colebrook–White equation. It was derived using Steffensen's method. [12] The solution involves calculating three intermediate values and then substituting those values into a final ...

Block on a ramp and corresponding free body diagram of the block. In physics and engineering, a free body diagram (FBD; also called a force diagram) [1] is a graphical illustration used to visualize the applied forces, moments, and resulting reactions on a free body in a given condition. It depicts a body or connected bodies with all the ...
A Nigerian man who has spent 10 years on death row for stealing some hens and eggs has been promised a pardon by the governor of the south-western Osun state.
As Joe Biden's presidency nears its end, he bid farewell to a "dear friend" in former President Jimmy Carter.. Carter, 100, died on Sunday at his home in Plains, Georgia. Biden released a ...
