Question

Water flows in a tank 150m x 100m at the base through a pipe whose cross section is 2dm x 1.5dm at the speed of 15km/h in what time will the water be 3m deep

Answer 1

Answer:

Volume of water in the tank, when depth is of 3 m,

V = 150 × 100 × 3 = 45000 m^3

Rate of volume of water flowing = 2 × 1.5 × 10^-2 × 15000 m^3/hr = 450 m^3/hr

Thus,

Time taken = 45000/450 hr = 100 hours
