Academics

Water is supplied to an office building 44.0 m high through a pipe at ground level.

(a) Find the minimum pressure in the supply pipe so that water can reach the top floor of the building.

(b) Suppose the pressure in the supply pipe is designed so that water can flow out through a much smaller pipe on the top floor at a speed of 5.35 m/s. Find the pressure in the larger pipe on the ground floor.
