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
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
