There's a couple of recent threads on friction - rather than hijack those here's a new thread with a few questions I have. What I'm trying to understand...
TheD4,D5, andD6cells represent thePipe Roughness,Pipe Diameter,andReynolds Numberrespectively. Moreover, usetheLOGfunctionaccording to the equation. Navigate to theE9cell and calculate the difference between the right side and the left side: =D9-C9 C9andD9cells point to theLHSandRHS,respectiv...
calculate how the rate will change when you change the radius. It's also possible to maintain the radius constant and vary the pipe length, although this would require a different constant. Comparing predicted to measured values of flow rate tells you how much turbulence and friction affect the...
How can I calculate entropy or entropy generation in CFD-Post for flow (incompressible) in pipe from fluid flow and heat transfer fields (i.e. solving momentum and energy equations)? I didn't find much in ANSYS documentation except a formula "s-s_ref=c_p*log*(T/T_ref)" for constant...
The gasoline charge in the cylinder explodes, driving the piston downward. Exhaust stroke - Once the piston hits the bottom of its stroke, the exhaust valve opens and the exhaust leaves the cylinder to exit through the tail pipe. The manholes in question are already filled with an expanding ...
Secondly i don't know how to calculate The Darcy friction factor for turbulent flow (as is the case here initially) for K = f * Leq / D. Also what does Leq represents. I'm afraid I have no idea about most of what you say. It might help to tell you that before...
Coulomb's law made it possible to calculate the electrostatic force between any two charged objects, but it didn't reveal the fundamental nature of those charges. What was the source of the positive and negative charges? As we'll see in the next section, scientists were able to answer tha...

Prepare for bad weather conditions on the road by (1) taking your car to a mechanic before a trip, (2) building an emergency kit, and (3) mapping out the route ahead of time.
Water creates pressure or resistance, at predictable rates, so we can calculate pump head as the differential pressure that a pump has to overcome in order to raise the water. Common units are feet of head and pounds per square inch. (A pump characteristic curve calculator might offer ...
