Answer:
Water is flowing through a cylindrical pipe of internal diameter 2cm, into a cylindrical tank of base radius 40 cm at the rate of 0.7m/sec. By how much will the water rise in the tank in half an hour?
For pipe, r = 1cm
Length of water flowing in 1 sec, h = 0.7m = 7cm
Cylindrical Tank, R = 40 cm,
rise in water level = H
Volume of water flowing in 1 sec = πr2h
= π x 1 x 1 x 70
= 70π
Volume of water flowing in 60 sec = 70π x 60
Volume of water flowing in 30 minutes = 70π x 60 x 30
Volume of water in Tank = πr^2H
= π x 40 x 40 x H
Volume of water = Volume of water
in Tank flowing in 30 minutes
π x 40 x 40 x H = 70π x 60 x 30
H = 78.75 cm
