Yes, the cross-sectional area of the pipe changes along the x-direction. We would like to study the relationship between the rate of change of pressure and the rate of change of pumping power. Sarah

Our problem is that we measured the rate of change of pressure of a liquid at different length of a pipe, for example, x=0, x=5cm, ... etc, caused by a pump at x=0-15cm=-15cm and got a result that at x=0, dP1/dt1 = -dP2/dt2, where dP1 is the pressure difference over a fixed interval, del t1, and...

Dear Sir/Madam, I would like to know if I can apply the conservation of momentum to the rate of change of pressure at a fixed position (for e.g. x=0) as follows: dP1/dt=-dP2/dt where dP1 is the pressure changes over a fixed interval of time (del t1) and dP2 is the pressure changes over...
