A liquid with sp. gr.= 1.12 flows through a pipe with velocity 1 m/s. The diameter of the pipe is 4 in. Calculate: (i) The mass flowrate (kg/s), and (Ibm/min) (ii) The volumetric flowrate (m³/s), and (ft³/min) Kg Ans.: (i) 9.08 1198.5 lb/min (it) 0.0081 m³/s. 17.15ft³/min

A fluid is flowing with a mass flow rate om in a smooth horizontal pipe of length L and diameter D as the result of a pressure difference P.-PL. The flow is known to be turbulent. The pipe is to be replaced by one of diameter D/2 but with the same length. The same fluid is to be pumped at the same mass flow rate om. Calculate the pressure difference that will be needed to achieve this flow rate.
