A process fluid is pumped from the bottom of one distilation column to another using a tentrifugal pump. The line is standard commercial steel pipe 75mm internal diameter. From the column to the pump inlet is 30m long and contains 5 standard elbows and 1 fully open gate valve. From the pump outlet to the second column, the line is 300m and contains 10 standard elbows, 4 gate valves (operated fully open) and 1 flow control valve. The fluid level in the first column is 4m above the pump inlet. The operating pressure in the 1st column is 1.05 bara and that of the 2nd column 0.3bar gauge. Determine the operating point on the pump characteristic curve when the flow is such that the pressure drop across the control valve is 35kN/m2. The physical properties of the fluid are: A process fluid is pumped from the bottom of one distilation column to another using a tentrifugal pump.
