Solution

It is given that

Length of the tank (l) = 80 m

Breadth of the tank (b) = 25 m

= 2500 cm

Area of the cross section of the pipe is 25 cm²

The water flows at the rate of 16 km/hr.

We are asked to find the level of tank raised in 45 minutes

In 45 minutes, the water through the pipe will go,

Area of the cross-section of the pipe is 25 cm².

So, the quantity of the water poured in 45 minutes,

Let,

Height to which the water is raised

So,

In 45 minutes, the water level rises by .
