Consider the information given below.
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: 12 m), the pressure is 20 kPa and the velocity is 2 m/s. Density of water is 1000 kg/m3 and acceleration due to gravity is 9.8 m/s2.
Which of the following is true?1
Flow is from S1 to S2 and head loss is 0.53 m
2
Flow is from S2 to S1 and head loss is 0.53 m
3
Flow is from S1 to S2 and head loss is 1.06 m
4
Flow is from S2 to S1 and head loss is 1.06 m
