Water flows into a tank which is 200 m long and 150 m wide, through a pipe of cross-section (0.3m x 0.2m) at 20 km/h. In what time will the water level be 12m ?

Question

Accepted Answer

Volume of water collected in the tank in 1 hour ⇒ (0.3 × 0.2 × 20km × 1000mts) = 1200 m cubic If after t hours, the water is at height of 12m, 1200t=200×150×12 ⇒ t = 300 Hours.
