Q2. 50 marks Water at 20°C is pumped at 5.7 m3 min-1 from the lower to the upper reservoir, as in Fig. 2. The free surface of the upper reservoir is at height Z2 = 46 m, and of the lower reservoir at 21 = 15 m. The pipe diameter before and after the pump is D= 15 cm. Pipe friction losses are approximated by h = 27v2/(29), where V is the average velocity in the pipe. The gravitational acceleration...

2. Water is pumped from a reservoir at rate of 2 f?/sec. from a reservoir 20 ft above the pump to a free discharge at 90 above the pump as shown. The pressure at intake to pump is 5 psig and pressure at discharge side of the pump is 50 psig. All pipes are commercial steel and 6 inches in diameter. Find (a) the head supplied by the pump.

A pump delivers water at 200C between a reservoir and a water tank that is 75[ft] higher than the reservoir. The suction side of the system consists of a cast iron pipe of 1[ft]diameter with a strainer (Ks= 2.5) and four 90-degree bends at R/D= 5. The discharge side of the system includes a 1000[ft] long commercial steel pipe with 12” diameter followed by a gate valve. The NPSH required for the pump is 10[ft], and the design discharge is...

The value of (NPSHfor a pump is given by the manufacturer as 20 ft. Water is being pumped from a reservoir at a rate of 25 cfs. The water level in the reservoir is 6.0ft below the pump. Atmospheric pressure is 14.7 psia and water temperature is 40℉. If the total head loss in the suction pipe is 4.0 ft, is the pump safe from cavitation effects?

Water is pumped from a well to a water tower (an above-ground reservoir) through a 330 ft long galvanized iron pipe (ε-0.0005 ft) with a 2-in diameter. The water surface in the well is 10 ft below the ground and the water surface in the tower is 60 ft above the ground. The water is to be delivered at a rate of at least 370 L/min. The sum of the minor loss coefficients is 2.1 a) Using the pump performance...

In order to provide irrigation, water has to be pumped to an elevation 120 m through a 600 mm pipe where the pressure required at the higher elevation is 172 kPa. The source of the water and the discharge point are at atmospheric pressure. Irrigation requirements dictate that water must be pumped at the rate of 1m3/sec. The loss of head due to friction and other factors is estimated to be 2.4m. Elevation of the water source is 60 m....
