A liquid food at 50C is being pumped at a rate of 3 m³/h in a sanitary pipe 1.4 inches in diameter and a roughness of 4.6 x 10^-5m through a distance of 200m in a horizontal direction and then through a vertical height of 8m. In the pipe, there is a globe valve for which the frictional loss can be taken as 300 pipe diameters and the other pipe fittings equivalent to 32 pipe diameters. There is a heat exchanger which has a head loss of 1.5m. What power must be supplied to the pump if it is 65% efficient. The viscosity and density of the liquid are 0. 003Pa.s and 1033kg/m³

From Moodys Diagram take friction factor, f= 0.008. (Please note you are still required to show ALL relevant calculations to arrive at this point of obtaining friction factor, f).

Mechanical Energy Equation given below; Assume that P=0.

Conversion Factors: 1 inch=0.0254m ; 1Pa.s=1 kg/ms
