Water is pumped from a lower reservoir to a higher reservoir by a pump that provides 20 kW of shaft power. The free surface of the upper reservoir is 45 m higher than that of the lower reservoir. If the flow rate of water is measured to be 0.03 m3/s, determine (a) mechanical power that is converted to thermal energy (in kW) during this process due to frictional effects and (b) the pump efficiency (%). Take the density of water...

Water is pumped at a rate of 10 litres/s from a pond to an open tank. The pipe is 30 m in length and made of 1-in, Schedule 40 (I.D = 0.02664 m) commercial steel pipe with the surface roughness of 0.0018 in (0.045 mm). In the pipelines, there are two gate valves, one globe valve and three 90o long-radius elbows. The surface of water in the tank is 3 m above the surface of the pond. (The density of...

(b) Figure Q3 shows a design of a plumbing system to be used in a new building. Water at 20°C is free to be pumped from reservoir A to another reservoir B at a higher elevation through two 30 m long pipes connected in parallel on a common elevation level. The difference between the water surface elevations is 10 m. The pipes are made of commercial brass and the diameters of the two pipes are 4 cm and 8 cm....

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...
