The speed of water is `2m//s` through a pipe of internal diameter 10 cm. What should be the internal diameter of nozzle of the pipe if the speed of water at nozzle is `4m//s`?

What should be the diameter of a water drop so that the excess pressure inside it is 80N/m^2 ?

The pressure of water inside the closed pipe is 3xx10^5 N//m^2 . This pressure reduces to 2xx10^5 N//m^2 on opening the valve of the pipe. Calculate the speed of water flowing through the pipe (rho=1000 kg//m^3) .

Water is flowing continously from a tap having a base of internal diameter 8 xx 10^-3 m . Calculate the diameter of the water stream at a distance of 2 xx 10^-1 below the tap. Assume that the water velocity as it leaves the tap is 4 xx 10^-1 m//s .

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

The speed of swimmer in still water is 20 m/s. The speed of river water is 10 m/s and is flowing due east. If he is standing on the south bank and wishes to cross the river along the shortest path, the angle at which he should make this strokes w.r.t.north is given by:

An ideal fluid flows through a pipe of circular cross section with diameters 5 cm and 10 cm as shown. The ratio of velocities of fluid at A and B is

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?

An ideal fluid flows through a pipe of circular cross section made of two sections with diameters 2.5 cm and 3.75 cm. The ratio of the velocities in the two pipes is

Water is flowing therough a tube of diameter 1 cm at 8 cm/s. Taking eta=10^(-2) poise the flow of liquid and Reynold's number are
