Q1. (20 marks) A fluid flows through a horizontal pipe at a rate
of 120 L/s. The larger and the smaller sections have diameter 22 cm
and 10 cm (Fig. 1). Take the water density to be 1.00  103 kg/m3 .
(a) Compute the fluid speed at two sections of the pipe. (b)
Knowing that the height h in Fig. 1 is 1.37 cm, find the fluid
density
