Problem 1
Refer to the figure for the questions below. You can ignore losses around bends.
a) A 40-m long 4-inch diameter commercial steel pipe connects Reservoir A with Reservoir B. The water temperature is 10oC. Find the flow rate if the pressure at A is atmospheric and the globe valve is fully open. The minor loss coefficient for the check valve is 12.
b) Find the pressure at each bend designated in the figure (Points 1 2 3 4 5 and 6).
c) Find the minimum pressure needed in Reservoir A to keep positive gage pressure throughout the system.
