1. One pump is not enough to pump water to a very high tank. If you use two pumps (to increase h), how are you going to install them?

(a) in parallel

(b) in series

2. For turbulent flow of all pipes, friction factor (f) depends on:

(a) Reynolds number (Re) only

(b) relative roughness (e/D) only

(c) both Re and e/D

4. For a pumping system, which tends to cause cavitation?

(a) placing the pump close to the source reservoir to minimize head loss

(b) setting the pump at a higher elevation relative to the reservoir water surface

5. Show the SI dimension and BG unit of specific energy (E)

1) A tank is full of water. Find the work W required to pump the water out of the spout. (Use 9.8 m/s2 for g. Use 1000 kg/m3 as the weight density of water. Assume that a = 4 m, b = 4 m, c = 12 m,and d = 1 m.) W = ___ J I got 5017600 then in scientific notation it would be 5.0176 X 10^6, then in Juls in would be 5.02? I got the answer...

A pump lifts 1000 (liters) of water from ground to a tank on the roof of a building 100 (m) high. What is the potential energy in the water? [ 1 (liter) = 1000 cm3 ]. Show all your steps to the solution. A skier is coming downhill. At one point she is 50 (m) above the bottom of the hill and moving at 20 (m/s). What is her speed as she reaches the bottom of the hill? 22.3 (m/s)...

2. A pump delivers 30o C water from a supply reservoir to an elevated storage tank at a discharge rate of 120 litres/sec. At this discharge the manufacturer’s data indicates the net positive suction head (NPSH) for the pump is 6.0 m. The water surface elevation difference between the reservoir and the tank is 45.0 m. The total length of pipe between the two is 150.0 m, 10.0 m of which is located on the suction side of the pump....

A 32 inch diameter pump handling 22000 GPM flow of water coming from an atmospheric tank storage is running at 1170 rpm. The water temperature can be taken at 25 C. The suction line is 20 meter long at 6 inch diameter. The pump suction is 0.4 meter above ground level. The tank storage is elevated on a 1 meter high platform. Assume friction factor of 0.02. Specific Gravity of water at 25 C is 0.9967. NPSH required is 34...

(20.1) A very large tank of water with its top open to the air has a small hole in its side. The hole lies at a depth of 9.8m below the top surface of the water. Compute the speed with which water spurts out of the hole. [Take g = 10m/s2 and assume that the hole is small enough that the water level in the tank is changing very slowly.] (20.2) Modern construction standards require that roofs be securely attached...

It is noteworthy that during a holiday trip, the water is discharged from a high tank with a 30 cm diameter plastic pipe into a stream in the valley, and the idea of generating power from this water comes to your mind. The bird flight from the reservoir stream is 100 m and the height difference between the free water surface and the stream in the tank is 75 m. (a) Show the relationship between the water flow in the...

A small water pump is used for an irrigation project. The pump takes water in from a river at 10oC, 100 kPa at a mass flow rate of 16.83 kg/s. The exit line enters a pipe that goes up to an elevation 26.15 mm above the pump and river, where the water runs into an open channel. Assume the process is adiabatic and that the water stays at 10 oC. Find the required pump work.

5. (Mixing Problem) A very large tank is initially filled with 100 gallons of water containing 5 pounds of salt. Beginning at time t = 0, a brine solution with a concentration of 1 pound of salt per gallon flows into the top of the tank at 3 gallons per second, the mixture is stirred, and the mixture flows out of the bottom of the tank at 2 gallons per second. (a) Letting w = pounds of salt in the...
