Question

Water is flowing at the rate of 15 km per hour through a pipe of diameter 14 cm into a rectangular tank which is 50 m long and 44 m wide. Find the time in which the level of water in the tanks will rise by 21 cm.

Answer 1

In cylinder,

r = 7cm = 0.7m

l = 15 km = 15000 m

In tank

l = 50 m

b = 44 m

h = 0.21 m

Volume of water in tank = lbh

= 50 x 44 x 0.21

= 462 m³
