. A farmer connects a pipe of internal diameter 20 cm from a canal into a cylindrical tank in her
field, which is 10 m in diameter and 2 m deep. If water flows through the pipe at the rate of 3 kilometer per hour, in how much time will the tank be filled?
Best Answer
Explanation:
Radius of cylindrical tank (R) = 10/2=5m
Depth of the cylindrical tank(H)=2m
Radius of cylindrical pipe(r)=20/200=0.1m
Length of water that flows through the pipe in one hour =3km
Length of water that flows through the pipe in one minute(h)=3km/60
=3×1000m/60
=50m
Volume of water that flows through pipe in t minutes = volume of water in cylindrical tank
Hence, the cylindrical tank will be filled in 100 minutes.
Final answer: Hence, the cylindrical tank will be filled in 100 minutes.
