How is water drawn up from a well by a water pump ?

(A) : For drawing water with a bucket from a well by a person usage of pulley reduces the force required rather than drawing directly (R) : When water is drawn with a bucket directly from well normal reaction on man is more man than that when he draws it using a pulley

How is heavy water prepared from ordinary water ? Discuss its important physical and chemical properties.

Water is drawn from a well in a 5kg drum of capacity 55L by two ropes connected to the top of the drum. The linear mass density of each rope is 0.5kgm^-1 . The work done in lifting water to the ground from the surface of water in the well 20m below is [g=10ms^-2]

A man pulls a bucket of water from a depth of h from a well. If the mass of the rope and that of bucket full of water are m and M respectively, the work done by the man is :

A nuclear power plant generates 500 MW of waste heat that must be carried away by water pumped from a lake. If the water temperature is to rise by 10^@C , what is the required flow rate in kg//s ?

P is the atmospheric pressure and the pressure at the bottom of a tank of water is 3P. If the water is drawn out to lower the level of water by one fifth, then the pressure at the bottom of the tank will be

A pump is required to lift 1000 kg of water per minute from a well 20 m deep and ejects at a speed of 20 m/s. The power of engine is

A pump can take out 7200 kg of water per hour from a well 100 m. deep. The power of pump, assuming its efficiency as 50% will be

How much mass of water can be lifted by a pump motor of 9.8 kW in one minute to a height of 5 m ?

A pump is required to lift 1000kg of water per minute from a well 20m deep and eject it at a rate of 20ms^-1 . a. How much work is done in lifting water? b. How much work is done in giving in KE? c. What HP(horsepower) engine is required for the purpose of lifting water?
