A smooth pipe of diameter 200 mm carries water. The pressure in the pipe at section S1 (elevation: 10 m) is 50 kPa. At section S2 (elevation : 12m) the pressure is 20 kPa and velocity is 2 m/s. Density of water is 1000 kg/m3 and acceleration due to gravity is 9.8ms–2. Which of the following is TRUE?
(a) flow is from S1 to S2 and head loss is 0.53 m
(b) flow is from S2 to S1 and head loss is 0.53 m
(c) flow is from S1 to S2 and head loss is 1.06 m
(d) flow is from S2 to S1 and head loss is 0.53 m
