Deciding Direction of the Flow - GATE ME '10
A smooth pipe of diameter 200 mm carries water. The pressure in the pipe at section S1 (elevation : 10 m) is the 50 kPa. At section S2 (elevation : 12 m) the pressure is 20 kPa and velocity is 2 m/s. Density of water is 1000 kg/m^3 and acceleration due to gravity is 9.8 m.s^−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
