Anyone know where the coefficient of discharge comes from… seems to be one of engineerings finest mysteries
@CasparHewettFluids 2 күн бұрын
It is an empirical parameter which is intorduced to take account of energy losses - for the idealised case the coefficient is one. Thus, for a real weir we haev to calibrate to find cd.

Please someone help me out, I have a tube well with 3 inches delivery and water is pulled by a 7.5 hp submersible pump system. What I am planning to do is to reuse the water force which falls out and to produce electricity or mechanical power. What output can be obtained and which system is more efficient, micro hydro turbine or a propeller.

Hi, Thank you for the good explanation. I'm personally interested in how you can use it to solve a nonlinear reaction diffusion equation. How would you go about analysis its stability in relation to the Von Neumann Stability condition? Thank you in advance.

Why is the momentum force in the opposite direction as the pressure force? Seems like they would both be acting in the same direction, no?🤔
@CasparHewettFluids 7 ай бұрын
There are two elements of the momentum. The momentum into the control volume, which acts in the same direction as the pressure and the momentum out of the control volume which is in the opposite direction to the pressure
@CasparHewettFluids 7 ай бұрын
The pressure forces are those acting on the control volume, which is why they are both inward

@mohsen9828 Жыл бұрын
if we consider a 90-degree bend pipe, with initial conditions as follows: inlet velocity 15 m/s, no change in cross-section area (let's say radius of 0.2 m), and we only know outlet pressure is equal to atmospheric pressure. Is Bernoulli's equation satisfied? does it mean outlet and inlet pressure are the same? in that case, there's no flow?!
@CasparHewettFluids 5 ай бұрын
Bernoulli equation is satisfied within the pipe so pressure will be constant if the pipe is horizontal, resulting in a jet at the outlet. The pressure in the pipe can't be atmospheric pressure if the water has a velocity! Conditions are different once water reaches the outlet. Thus, the problem you pose can't be solved. There is insufficient information. You would need to know the pressure in the pipe.

Would the vertical pressure force still be oriented downward if the curved pipe was facing down not up?
@CasparHewettFluids Жыл бұрын
No, the pressure force always acts inwards towards the control volume so it would be acting upwards if the pipe were facing downward.

How do we determine the direction of pressure force?
@CasparHewettFluids 2 жыл бұрын
We are considering the forces on the control volume, so the pressure force is acting inwards on that control volume (there is an equal and opposite pressure force outward, but that isn't relevant to the calculation) thus it is acting to the right on the left hand side and to the left on the right hand side.
