A 20 degree Brix apple juice is being pumped from an open tankthrough a 1-in nominal diameter sanitary pipe into a second tank ata higher level. The mass flow rate is 1 kg/s through 30 m ofstraight pipe with two 90 degree standard elbows and one anglevalve. The supply tank maintains a liquid level of 3 m and theapple juice leaves the system at an elevation of 12 m above thefloor. Compute the power requirements of the pump.
Given: Juice density is 997.1 kg/m3 and viscosity is 2.1*10-3Pa.s. Pump efficiency is 60%.
