The workdone by pressure in forcing `1m^3` of water through a pipe if the pressure difference across the pipe is `10^4` Pa, is

How much work is done by pressure in forcing 2.0 m^(3) of water through a pipe having an internal diameter of 13 mm if the difference in pressure at the two ends of the pipe is 1.0 atm?

Two horizontal pipes of diameter 4 cm and 8 cm are connected together and water is flowing through the first pipe with a speed of 5 ms ""^(-1) . Calculate the speed and pressure of water in the second pipe if water pressure in the first pipe is 3 xx 10^(4) N//m^(2) .

Lasya is watering the plants in her graden with a pipe of area of cross- section 'A' and observed that the force of water from the pipe is 'F' .Find the change in area of caross section of the pipe to attain a pressure difference which is 1.5 times that of the intial.

Water is flowing through two horizontal pipes of different diameters which are connected together. In the first pipe the speed of water 4 m/s and the pressure is 2.0xx10^(4) N//m^(2) . Calculate the speed and pressure of water in the second pipe. The diameter of the pipes the diameter of the pipes are 3 cm and 6 cm respectively.
