µ A pump is being used to transport a liquid food product (p = 1000 kg/m³, μ = 1.5 cP) from a holding tank to a filling machine at a mass flow rate of 2 kg/s. The liquid level in the holding tank is 10 m above the pump, and the filling machine is 5 m above the pump. There is 100 m of 2-in nominal diameter sanitary pipeline between the holding tank and the filling machine, with one open globe valve and four regular 90° flanged elbows in the system. The product is being pumped through a heat exchanger with 100 kPa of pressure drop due to friction before filling. Determine the theoretical power requirement for the pump.
