question

Oil is to be pumped at a rate of 1) 10 lb/sec, 2) 50 lb/sec through a horizontal pipe of 4 in.diaand 5280 ft length. Calculate the drop in pressure and the theoretical horse-power developed, if the oil density is 59.3 lb/ft^3 and the viscosity is 50 cp. For the case of turbulent flow, assume the Darcy friction factor to be 10 per cent higher than calculated for a smooth pipe.
