a. Fresh water reservoirs A and B are connected by two pipes. Steady state conditions prevail.Determine the total volumetric flow rate of water from reservoir A to reservoir B given:

Pipe (i) 500m long, 250mm diameter, friction factor f = 0.0041 Pipe (ii) 550m long, 450mm diameter, friction factor f = 0.0037 The minor losses are for both pipes: Entry loss,k = 0.5 Exit loss,k = 1.0 b. A venturi meter is fitted to a 300 mm diameter pipeline carrying 105 litre/s. The reading on a differential mercury (pman = 13600) manometer connected between inlet and throat is 0.5m. The meter coefficient is 0.98. If the discharge of the pipe is given by
