A turbo pump transfers water from tank 1 to tank to tank 2 as shown in the picture below. The diameter of the piping system is D= 4in and the total length of pipes is L=620 ft. the elevation difference is Z1-Z2= 30ft. Use the chart for KL values.

a) determine the flow rate (Q)

b) power of the pump in HP

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 O simultaneously. You are required to set up the equations and carry out at least two iteration steps. (2) A B (0 Gate Valve II (closed) (1) Gate Pump Valve I (open) KL 1.3 Fittings and Valves 90° elbow (flanged & long radius) Basket Strainer T-joint (line flow) T-joint (branch flow) Exit Gate valve (fully open) 1.0

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...

A pump that is 80% efficient pumps water from the lower tank to the upper tank at a flow rate of 0.01 m/s through 70 meters of 10-cm diameter pipe. In this system there are two regular, screwed 90 degree elbows and a fully open screwed angle valve. Assume the reservoir exits and entrances are sharp. The friction factor,f, of the pipe is 0.02. What horsepower pump is needed to achieve this flow rate? Use: Pwater = 998 kg/m2; Mwater...
