In large buildings, hot water from the water tank is continously recurculated in a loop to avoid long waits for hot water while cold water drains out of the pipe first. A certain recirculating loop is 30 m long and uses 22 mm diameter polyethene pipes which have a surface roughness of 0.0005 mm. The loop contains six 90 degree elbows, each with a local loss coefficient of 0.3. If the average flow velocity is 2.5 m s1, determine the required power input for the recirculating pump if its efficiency is 80%.
A pump is installed with a suction pipe of 200mm and a delivery pipe of 150mm (λ=0.02) in diameter to pump 0.08m3/s. The delivery pipe is 280m long.

Question 2A large vat contains water, which contains a drainage pipe at a height h1, as shown infigure 2. The drainage pipe has a length L. = 0.4 m, and a radius R = 15 mm, and releaseswater to the atmosphere at a flow rate Q.
