A pump is being used to transport a liquid food product (p = 1250 kg/m³, µ = 1.5 cP) from a holding tank to a filling machine at mass flow rate of 2.5 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 open globe valve and three regular 90° flanged elbows in the system. The product is being pumped through a heat exchanger with 120 kPa of pressure drop due to friction before filling. Complete the process diagram and determine the actual power requirement if the efficiency of the pump and the motor are 85 % and 80%, respectively.

Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

Question

A pump is being used to transport a liquid food product (p = 1250 kg/m³, µ = 1.5 cP) from a holding tank
to a filling machine at mass flow rate of 2.5 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 open globe valve and three regular 90°
flanged elbows in the system. The product is being pumped through a heat exchanger with 120 kPa of
pressure drop due to friction before filling. Complete the process diagram and determine the actual power
requirement if the efficiency of the pump and the motor are 85 % and 80%, respectively.

I need help on this question: According to the question: a) If the pipe connected to the pump inlet has a diameter of 24 mm with length (LCP) of 5 m and Darcy friction factor of 0.03, what would be the actual head rise across the pump for a case where the pump outlet pressure is 200 kPa? The difference in height between pump inlet and outlet is 0.25 m, the tank exit is sharp-edged, and the water level in the tank to the tank exit pipe (HWL) is 2 m. Also, consider that the flow velocity inside the tank is negligible. The value of the actual head rise across the pump is = ? b) What would be the pump motor power if the efficiency is 60%? The value of the pump motor power is = ?
A centrifugal pump must be installed 6 m above the water level in a tank. the bomb will operate at a rate of 0.01 m³/s. The manufacturer suggests a pump with NPSHR at this flow rate of 2.5 m. Neglect friction losses, with the exception of a heat exchanger between the tube inlet and pump suction, which has a loss coefficient Cf = 15. The pipe diameter is 15 cm and the pressure of water vapor at 30°C is 4.246 kPa. Is this pump suitable for the given conditions?
