Water is flowing at the rate of 5 km/hour through a pipe of diameter 14 cm into a rectangular tank,which is 50 m long and 44 m wide.Determine the time in

which the level of water in the tank will rise by 7 cm.

Volume of water in rectangular tank = area of rectangular tank × hight = 44*50*0.07 = 154m³ area of pipe = π*r² = (22/7)×(0.07)² = 0.0154m² volume flow rate = area of pipe×flow rate = 0.0154×5000m/hr = 77m³/hr time = volume/volume flow rate = 154/77 time = 2 hrs.
