Problems (4) to (8) below are based on Example Problem 13.4 Example Problem 13.4 FIGURE 13.41 System for Example Problem 13.4 80 ft Figure 13.41 shows a pumped fluid flow system that is being designed to transfer 225 gal/min of water at 60°F from a lower vented reservoir to an elevated tank at a pressure of 35.0 psig. The suction line has 8.0 ft of steel pipe and the discharge line has 360 ft of pipe. Pipe sizes are shown in the figure. Prepare the SRC for this application, considering flow rates from zero to 250 gal/min, computing head values in 50 gal/min increments. 811 31/2-in Schedule 40 steel pipe Fully open gate valve 21/2-in Schedule 40 steel pipe - Pump -p35.0 psig Swing-type check valve Standard elbow Butterfly valve Flow FIGURE 13.28 Complete pump performance chart for a 2 x 3-10 centrifugal pump at 3500 rpm.
