Calculate the velocity head of water which is flowing with a velocity of 5 m/s in a horizontal pipe.

A pipe 2 cm in diameter has a constriction of diameter 1 cm. What it’s the velocity of flow at the constriction. If velocity of flow in the broader region of the pipe is 5 cm/s?

Water is flowing through a horizontal tube of non-uniform cross-section. At a place, the radius of the tube is 1.0cm and the velocity of water is 2m//s . What will be the velocity of water where the radius of the pipe is 2.0 cm ?

48.A block of mass 5kg is at rest on a smooth horizontal surface Water coming out of a pipe horizontally at the rate of 2kg/sec ,hits the block with a velocity of 6m/sec.The initial acceleration of the block is

A storage tower supplies water, as shown in the figure. If P_(0) is the atmospheric pressure h = height of water level, g = acceleration due to gravity, rho= density and v = velocity of flow in the horizontal pipe at B, then the pressure at B is -

The velocity of a boat in still water is 10 m//s .If water flows in the river with a velocity of 6 m//s what is the difference in times taken to cross the river in the shortest path and the shortest time.The width of the river is 80 m .

Water enters a horizontal pipe of non uniform cross section with a velocity of 0.5 m/s and leaves the other end with a velocity of 0.7 m/s. the pressure of water at the first end is 10^(3) N//m^(2) . Calculate pressure at the other end. (Density of water =1.0xx10^(3)kg//m^(3) )

The rate of flow of water through a horizontal pipe of changing cross section is 100 litres per hour. Calculate the velocity of water flow at a point where diameter of the tube is 4 cm?

Calculate the velocity with which water emerges from an orifice in a tank if the gauge pressure is 2 xx 10^5 N/m before the flow starts.
