A pump is being used to transport a liquid food product (density p=1000kg/m^3, viscosity 0.001 Pa s) from holding tank to filling a 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 diamter sanitary pipe between the holding tank and the filling machine, wiht one open globe valve and four regular 90° flanged elbows in the system. Within the system, there is a heat exchange which causes 100 kPa of pressure drop due to friction. The holding tank is open to atmosphere, and filling machine is running at a pressure of 1.5 atm. The diamter of the filling machine pipe is 3cm. A: What is the volume flow rate of the system? B: What is the diamete of the pipe? C: What is the average velocity inside the pipe? D: What is the reynolds number of the flow in the pipe? E: What is the flowing type?
