A pump transports water from Tank 1 to Tank 2 through a constant-diameter piping system as shown below (not to scale). The flow rate is controlled by two gate valves, the gate valve I controls the main pipeline, while the gate valve II controls the loop line from T-joint A to T-joint B. All pipes are galvanized steel pipe of diameter D = 4 in. It has a total length of Li2= 620 ft from tank 1 to tank 2. All fittings are flanged and the elbows are long radius. The elevation difference between the free surfaces of the two tanks is z2 -Z1 = 30 ft. For steady-state operation with the gate valve I fully open while the gate valve II fully-closed, determine the total flow rate Q in the pipe when the pump head is hpump = 120 ft. Also find out the power of the pump, W in hp. pump Note that you can write out both mass balance equation and energy equation of the head form for the control-volume enclosed by the free surfaces, (1) and (2), of the two tanks. You need to consider all minor head losses through fittings, valves, etc. (see the table given). To estimate the major head loss through the straight pipes, the Haaland equation is required to determine the friction factor f. An iteration process is required to find out the friction factor f and the flow rate Q simultaneously. You are required to set up the equations and carry out at least two iteration steps. B.

The system below shows a simplified schematic of an oil transfer system between tanks, from left to right: L L The oil specific gravity is 0.77 and its viscosity is 2.7 [cP). The pipes are horizontal and coaxial (neglect difference in height between suction and discharge). The tanks are closed but vented so that they are at atmospheric pressure ([atm]). Assume for simplicity that the liquid level in each tank is 2.5 (m) above the level of the pipes (in...
