3. Question
A mason connects a pipe with internal diameter 10 cm from the source of water supply into a tank of the cylindrical shape which has a radius of 20 m and height of 4 m . If the water flows through the pipe at the rate of 5 km/hr , in how much time will the tank be filled.
Correct
Well Done !
Incorrect
Incorrect Answer !
Explanation:For pipe :
Diameter = 10 cm radius = 5cm
Water flowing through the pipe in 1 hour = 5 km = 5000 m = 500000 cm
Volume of water through pipe in 1 hour = πr^{2}h = π X 5 X 5 X 500000 cm^{3}
Cylinder Tank :
Volume = πr^{2}h =π X 1000 X 1000 X 400 cm^{3}
Time required to fill the tank = ( π X 1000 X 1000 X 400) ÷ (π X 5 X 5 X 500000) = 32 hours
