Question 2
A large tank with a nozzle attached contains three immiscible, inviscid fluids as shown. Assuming that the changes in 
are negligible, the instantaneous discharge velocity is
are negligible, the instantaneous discharge velocity is Question 3
The arch of a bridge over a river in the form of semi circle of radius 4 m .The bridge width is 10 m .Due to a flood the water level raises 2 m above the crest of the arch. The horizontal thrust (in MN) on the half of the arch is ___
Question 4
A dam is constructed across river for the purpose of irrigation. The depth of water (H) stored on the upstream side of dam is 5 m. The total pressure exerted on the upstream face for 1 m length of dam (in KN) is (assume g =10 m/s2) 
Question 5
The value moment of hydrostatic force about the hinge for a gate defined by y = 2x2 will be (in kNm)…
Question 6
