Question:
4.17 A large elevated tank (Tank 1) is being used to supply water at 60°F to two tanks at a lower elevation (Tanks 2 and 3) as shown in Figure P4.17. All pipes are 5-nom sch 40 commercial steel and the globe valve is wide opened. The straight lengths of the piping in Sections AB, BC, and BD are indicated in the figure. The elevation of the free surface of the water in each tank is also indicated in the figure. Pumps are used to maintain the water level in each tank.
a. Determine the volumetric flow rate (gpm) delivered to each lower tank
(Tanks 2 and 3) for the conditions shown.
b. The globe valve is used in this application for flow control. Determine the effect of closing the globe valve by constructing two plots; (1) the total volumetric flow from Tank 1, and (2) the volumetric flow delivered to each of the lower tanks (Tanks 2 and 3). Show each of these volume flows as a function of the globe valve constant in the resistance coefficient equation
