Question

5. A house is situated 20 m above the datum. It has to be supplied water from nearby
reservoir. The pipe length from the reservoir to the house is 200 m, diameter is 30 cm,
flow has to be 0.2 m3/s. Friction loss allowed is 5+Z m and the pressure to be maintained
in the pipe in the house is 20 kN/m2. Also consider minor losses (entrance and outlet).
Calculate the height the reservoir has to be situated above the datum? Water in
reservoir is at atmospheric pressure. Calculate lambda (λ) of the pipeline. (Z is the last 3
