Question
Water flows into a tank which is 200m long and 120 m
wide, through a pipe of cross- section 0.3 m × 0.2 m at 20 km/hr. then the time ( in hr) for the water level in the tank to reach 9 m is ?Solution
Volume of tank = 200m x 120 m x 9m ; Volume filled in 1 hr by pipe = 0.3 m x 0.2 m x 20 km/hr = 0.3 x 0.2 x 20000m/hr = 1200m3 /hr ; So time required to fill the tank = (200 x 120 x 9m 3 )/1200m 3 = 180 hrs
