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

Ac cording to Bernoulli's theorem for the streamline flow of an ideal liquid, the sum of pressure energy/mass, kinetic energy/mass and potential energy /mass remains constant at every cross section, throughout the liquid flow. i.e., (P)/(rho) + (1)/(2)upsilon^2 + gh = cosntant, where the symbols have their usual meaning. Note that an ideal liquied is the one, which is perfectly incompressible, irrotational and non visous. Read the above passage and answer the following question ? (i) At what speed will the velocity head of a stream of water be equal to 40 cm ? (ii) What is the implication of Bernoulli's theorem in day to day life ?

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

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

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

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

What is pressure head and velocity head?

What are velocity head and pressure head?

A man can swim directly a stream of width 100m in 4 minutes, when there is no current of water and in 5 minutes when there is current of water. The velocity of the current of water in the stream is
