Question

7. Water is falling in a cylindrical tank from an inlet pipe at the rate of 10 litres per minute. If the diame
and height of the tank are I m and 7 m, respectively, find the time required to fill the tank. (Hint: Fi
the volume of tank, convert it into litres and then find the time.)​

Answer 1

Answer:

550 minutes or 9.167 hours

Step-by-step explanation:

First Calculate Volume of the Cylinder.

Volume of the cylinder = $\pi$r$x^{2}$h

                                      =3.14*0.5*0.5*7   (radius=diameter/2)

                                      =5.5 cubic meters

Next Convert cubic meters into liters

1 cubic meter = 1000 liters

5.5 cubic meters = 5500 liters

Calculation of Time

To fill 10 liters it takes 1 minute

Then to fill 5500 liters it takes 550 minutes (5500/10*1)

or in hours it is 9.167 hours (550/60)
