A smooth of diameter 500 mm carries water. The pressure in the at Section 'A' (elevation: 10 m) is 100 kPa. At section 'B' (elevation: 12 m) the pressure is 75 kPa and velocity is 4=m/s. Which of the following is true (g =10m/s2)
1
Flow from A to B and head loss is 1 m
2
Flow from A to B and head loss is 0.5 m
3
Flow from B to A and head loss is 0.5 m
4
Flow from B to A and head loss is 0.75 m
