# A pump is being used to transport a liquid food product (ρ 1000 kg/m 3, μ 1.5cP) from a holding tank to a fi lling machine at a mass fl ow rate of 2 kg/s. The liquid level in the holding tank is 10 m above the pump, and the fi lling machine is 5 m above the pump. There is 100 m of 2-in nominal diameter sanitary pipeline between the holding tank and the fi lling machine, with one open globe valve and four regular 90 fl anged elbows in the system. The product is being pumped through a heat exchanger with 100 kPa of pressure drop due to friction before fi lling. Determine the theoretical power requirement for the pump.

A pump is being used to transport a liquid food product
(ρ 1000 kg/m 3, μ 1.5cP) from a holding tank to a fi lling
machine at a mass fl ow rate of 2 kg/s. The liquid level in
the holding tank is 10 m above the pump, and the fi lling
machine is 5 m above the pump. There is 100 m of 2-in
nominal diameter sanitary pipeline between the holding tank
and the fi lling machine, with one open globe valve and four
regular 90 fl anged elbows in the system. The product is being
pumped through a heat exchanger with 100 kPa of pressure
drop due to friction before fi lling. Determine the theoretical
power requirement for the pump.
