I am basically looking at a flow before and after a venturi like device, however the inlet and outlet diameters are different.
Could I just use the mass flow* (enthalpy change)to get the power? where the enthalpy is cp*T?
If I don't have the temperatures, is there a way of just working it out...
Thanks very much for your answer and explanation!
Edit: What equation would be best to use? Would I also need to know the temperature at both the inlet and the outlet to get energy change for compressible flow?
Hi guys,
I have quick question about calculating the power lost in fluid flow.
So imagine there is a simple setup as in the attached image, where you know the mass flow in and out, pressures at inlet and outlet and the temperature at the inlet.
Is the equation to find the power lost or...
