Extracted text: Problem 7: The two pumps in problem 6 are now arranged in parallel. The static head is 40 ft. The pipe diameter is 9-in of 1200 ft length and the minor loss coefficient is 20. Determine the operating condition and power output (Q, head, and efficiency) and the power output for the system of two pumps. Use f= 0.022. What is the flow rate and efficiency of each pump?
