Question

3. A water tank has a capacity of 1000 litres. It is
in the shape of a cylinder. The length of the
cylinder is 1 metre. An electric motor pump set
is used to fill the water in the tank. This pumpset
lifts 120 litres of water per minute. What is the
velocity in the shift of centre of gravity of the
water tank?​

Answer 1

Answer:

35 l

Explanation:

The values of the cylinder having 1000 litres capacity is 1 m3.

Find the area of the cross section and the height of the cylinder.

If 120 litres of water is pumped into the cylinder for every one minute, then the level of water rises up by the rate of 120/1000m.

Will the C.G. of the water tank rise by 120/1000 m in one minute?

Now, find the change in C.G. of the water tank in one second by dividing (2) by 60 seconds
