1. A pipe carrying water tapers from a cross-section of 0.3 m2 at A to 0.15 m2 at B which is 6 m above the level of A. At A the velocity, assumed uniform, is 1.8 m ·s−1 and the pressure 117 kPa gauge. If frictional effects are negligible, determine the pressure at B.
2. A long bridge with piers 1.5 m wide, spaced 8 m between centres, crosses a river. The depth of water before the bridge is 1.6 m and that between the piers is 1.45 m. Calculate the volume rate of flow under one arch assuming that the bed of the river is horizontal, that its banks are parallel and that frictional effects are negligible.
