Question
2.7 Calculate the total equivalent length of 1-in. wrought iron pipe that would produce a pressure drop of 70 kPa due to fluid friction, for a fluid flowing at a rate of 0.05 kg/sec, a viscosity of 2 cP, and density of 1000 kg/m³. A solution of ethanol is pumped to a vessel 25 m above a reference level through a 25-mm inside diameter steel pipe at a rate of 10 m³/hr. The length of pipe is 30 m and contains 2 elbows with friction equivalent to 20 diameters each. Compute the power requirement of the pump. Solution properties include density of 975 kg/m² and viscosity of 4x104 Pa.s. 2.8 A capillary-tube viscometer is being selected to measure viscosity of a liquid food. The maximum viscosity to be measured will be 230 cP and the maximum flow rate that can be measured accurately is 0.015 kg/min. If the tube length is 10 cm and a maximum pressure of 25 Pa can be measured, determine the tube diameter to be used. The density of the product is 1000 kg/m³. 2.9
