At what speed will the velocity head of a stream of water be equal to 20 cm of mercury . Taking `(g=10ms^(-2))`.

At what speed the velocity head of a stream of water be equal to 40 cm of Hg

At what speed will the velocity head of stream of water be 40 cm?

At what speed will the velocity head of stream of water be 50 cm ? Use g= 10m//s^(2) .

At what speed, the velocity head of water is equal to pressure head of 40 cm of mercury?

Calculate the speed at which the velocity of stream of water will be equal to 30 cm of mercury column.

If the velocity head of a stream of water is equal to 10 cm, then its speed of flow is approximately

A particle is projected with initial velocity of hati+2hatj . The eqaution of trajectory is (take g=10ms^(-2))

A wide vessel of uniform cross- section with a small hole in the bottom is filled with 40cm thick layer of water and 30cm thick layer of kerosene.The relative density of kerosene is 0.8 .The initial velocity of flow of water streaming out of the hole is (take g=10ms^(-2) )

A block moving on a horizontal surface with velocity 20 ms^(-1) comes to rest because of surface friction over a distance of 40 m. Taking g = 10 ms^(-2) , the coefficient of dynamic friction is :

A projectile thrown with an initial velocity of 10 ms^(-1) at an angle with the horizontal, has a range of 5 m. Taking g=10 ms^(-2) and neglecting air resistance, what will be the estimated value of alpha ?
