. The velocity of efflux of an ideal liquid not depends on
A. area of orifice
B. the density of liquid
C. the area of cross section of the vessel
D. the depth of point below the free surface of the liquid
Sol: Velocity of efflux is where h is the height from the above point of water level to the hole, A1 is the cross-sectional area of vessel, A2 is the cross sectional area of hole.
