The system shown below uses a pump to transfer heavy fuel oil (T= 25°C) from the lower tank to the upper tank at the rate of 3600 L/min. All pipe is DN 100 Schedule 40 steel (total system length of 310 m) and the pressure line has two 90° long radius elbows and two 45º standard elbows. Valves are: fully open gate valve(s); 2 swing-type check valve, fully open butterfly valve. Determine: a. The head loss in meters due to pipe friction. b. The head loss in meters due to minor losses c. The required pump power in kW.

Question
The system shown below uses a pump to transfer heavy fuel oil (T= 25°C) from the lower tank to the upper tank at the rate of 3600 L/min. All pipe is DN 100 Schedule 40 steel (total system length of 310 m) and the pressure line has two 90° long radius elbows and two 45º standard elbows. Valves are: fully open gate valve(s); 2 swing-type check valve, fully open butterfly valve.
Determine:
a. The head loss in meters due to pipe friction.
b. The head loss in meters due to minor losses
c. The required pump power in kW.
d. The pressure at the pump inlet (suction line is 10 m long). Is this pressure a vacuum?
e. The pressure at the pump outlet.
