The elevation difference between the water surfaces of reservoir A and reservoir B is 25 m. Point S represents the mid-length of the 500 m long pipe (i.e. 250 m). If the pipe diameter is 200 mm, velocity=2.2 m/s, roughness is 0.0025 mm and friction factor is 0.02 determine the highest elevation the pipe can reach (with respect to reservoir B) at the summit point (point S) without risking pipe cavitation.
Two identical groundwater pumps are operating 4.2 km apart. Each pump well structure has a tube diameter of 90cm. The original water table has an elevation of 60m and the hydraulic conductivity is 32m/day. However, it is maintained that the maximum drawdown (at the tube) is 14 m.

A 170-m long pipeline, composed of two pipes connected in series, discharges freely at a point 40 m below the water level at intake. The pipe projects into the reservoir.
