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 gained by the flow just (volume flow)*(pressure difference)? I know that you can use this to calculate the power required for a pump using liquids, does this also work for gases? Thanks!
