Solve the following examples: An electric pump has 2 kW power. How much water will the pump lift every minute to a height of 10m?

Find the mass of water lifted by a pump of power 0.5 hp to a height of 10 m in 49s.

Solve the following examples: Find the mass of water lifted by a pump of power 0.5 hp to a height of 5m in 98 seconds.

A person trying to lose weight by burning fat lifts a mass of 10 kg upto a height of 1m is 1000 time . Assume that the potential energy lost each time be lower the mass is dissipated . How much far will be use up considering the work done only when the weight is lifted up ? Far supplies 3.8 xx 10^(7) J of energy per kg wich is canverted to mechanical energy with x 20 % efficiency rate Take = 9.8 ms^(-2)

A cylindrical tank is filled with water to a level of 4 m. A hole is opened at a height of 60 cm from bottom. The ratio of the area of the hole to that at cross-sectinal area at cylinder is 0.2. Then the velocity with which water is coming out is (g = 10m//s^(2))

The heart of man pumps 5 liter of blood through the arteries per minute at a pressure of 150 mm of mercury. If the density of mercury be 13.6 xx10^3 kg//m^3 and g= 10m//s^2 , The power of heart in watt is

The heart of a man pumps 5 liters of blood through the arteries per minute at a pressure of 150 mm of mercury. If the density of mercury be 13.6xx10^(3) kg//m^(3) and g=10 m//s^(2) then the power of heat in watt is :

At a hydroelectric power plant, the water pressure head is at a height of 300 m and the water flow available is 100 m^3 s^-1 . If the turbine generator efficiency is 60%, estimate the electric power available from the plant (g=9.8 ms^-2)

An object of mass 5kg falls from rest through a verticle distance of 20m and reaches a velocity of 10ms^-1 . How much work is done by the push of the air on the object? (g = 10 ms^2)

A open U- tube contains mercury. When 11.2 cm of water is poured into one of the arms of the tube, to how much height does the mercury rise in the other arm from its initial level?
