The velocity of kerosene oil in a horizontal pipe is `5 m//s`. If `g = 10m//s^(2)` then the velocity head of oil wlill be

The velocity of kerosene oil in a horizontal pipe is 5 m/s. if g = 10 m/s^2 , then the velocity head of oil will be

Velocity of flow of water in a horizontal pipe is 10.0 m/s. Find the velocity head of water ( g=10m//s^(2) )

If velocity of flow is 4 m/s, then velocity head is

If velocity of flow is 4 m/s, then velocity head is

An oil drop of diameter 4 xx 10^(-6) m falls through air. iF the densities of the oil and air are 900 kg/m^(3) and 1.293 kg/m^(3) respectively and the coefficient of viscosity of air is 2.0 xx 10^(-5) Ns//m^(2) , then the terminal velocity of oil drop will be

A projectile is thrown with a velocity of 20 m//s, at an angle of 60^(@) with the horizontal. After how much time the velocity vector will make an angle of 45^(@) with the horizontal (in upward direction) is (take g= 10m//s^(2))-
