The water entering a hauze flows with a speed of `0.1ms^(-1)` through a pipe of 21 mm inside diameter .What is the speed of water at a point ,where pipe tapers to a diameter of 7mm?

In a horizontal pipe of non-uniform cross section, water flows with a velocity of 1ms^(-1) at a point where the diameter of the pipe is 20 cm. The velocity of water (ms^(-1)) at a point where the diameter of the pipe 10 cm is:

In a horizontal pipe of non-uniform cross section, water flows with a velocity of 1 ms^(-1) at a point where the diameter of the pipe is 20 cm. The velocity of water (1.5 ms^(-1)) at a point where the diameter of the pipe is (in cm)

Water is flowing at a speed of 0.5 m/s through a horizontal pipe of internal diameter 3 cm. Determine the diameter of the nozzle if the water is to emerge at a speed of 3 m/s.

Water flows through a pipe of diameter 8.0 cm with a speed of 10.0 m/s . It then enters a smaller pipe of diameter 3.0 cm . What is the speed of the water as it flows through the smaller pipe ?

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 ?
