A pump delivers 1000 L of water into a tank at a height of 15 m in 120s.Calculate the work done by the pump and its power?(g= 9.8m/s2)
Asked by SINDHUJA SRIVASTAVA | 9th Mar, 2015, 08:29: PM
Given height, h = 15 m
Mass of water = 1000 L × 1 kg/L = 1000 kg
Work done by the pump is equal the potential energy= mgh
= 1000 × 9.8 × 15
= 147 kJ

- When work is said to be done?
- How do you know that some entity is a form of energy ?
- Person A move from ground to third floor of his house through lift and person B do the same job with staircase who has done more job give reason
- in displacing a body 5 metre by a force of 50 Newton the work done is 125 joule find out the angle between the direction of force and displacement
- What is work done?
- A force of 40 Newton acts on a object at an angle of 45 degree with horizontal as a result the object is displaced horizontally through a distance of 14 metres calculate the work done by the force on an object
- Why energy is equal to work done?
- A force of 100 N acts through a distance of 10m.calculate the work done
- What would be the work done if (a) force on the object of zero? (b) displacement of the object is zero?
- Define work.
