Two water reservoirs, A and B, which have height difference of 12 m are connected by a pipe system consists of two cast iron pipes. The first has 60 mm diameter and 150m length while the second pipe has 120 mm diameter nd 150 m length. If the height of water in tank A is 1.5 m above its discharge point, calculate 1. flow rate for each pipe. 2. The diameter of a pipe 150 m long that could replace the two pipes and provide the same flow rate Viscosity of water = 1.16*10^(-3) pa.s =
