At the given flow rate of Q 1 m3s1 the pressure drop in the

At the given flow rate of Q = 1 m^3s^-1 the pressure drop in the this pipe is found to be 52 kPa/100 m. The pipe is 240 m long. What is the gauge pressure near the pump inlet (in kPa)? Do not enter the units in the answer box.

Solution

pipe length is= 240 m

pressure drop in the pipe= 52 kpa/100 m

the pressure drop in the pipe= (52/100) * 240 =129.6 kpa

velocity is same at the inlet and out let of pipe, so kinetic diatum loss is 0

diatum head change is 0 at 1 and 2

so the gauge pressure at the pipe inlet is 129.6 kpa
