Question

water is flowing at 7 m/s through a circular pipe of internal diameter of 4 cm into a cylindrical tank, the radius of whose base is 40 cm. Find the increase in water level in 30 minutes.​

Answer 1

Answer:

Step-by-step explanation:

Water is flowing at the rate of 7 m/s.

o length of pipe in which the water has traveled,

h = 7(1800) = 12600m

Radius of the pipe(r)= 1cm

Radius of the cylinder(R)= 40 cm

let the height of the water in the tank H

So,

Volume of water coming from the pipe = Volume of water in the cylindrical tank.

πr^2h = πR^2h

H = {(0.01)^2 X 12600}/(0.4)^2 = 7.875m..

hope it helps!!!
