Question

A liquid of density 1150 kg/m3 is flowing from point to point b which is 5 m above the point
a. the frictional losses in a pipeline of internal diameter 40 mm are 1 j/kg for a volumetric flow of 500cm3/s. if points a and b are at atmospheric pressure and the velocity at point a is zero, calculate the pump work done

Answer 1

the answer is 245
