Question

farmer connects A pipe of internal diameter 20 cm from the canal into a cylindrical tank in a field which is 10 m in diameter and 2 metre deep if water flows through the pipe at the rate of 3 km per hour in how much time will the tank be filled​

Answer 1

Answer:

Step-by-step explanation:

Volume of pipe = Volume of tank

⇒πr2 h=πR 2

H⇒(  100 /10 )  2 ×h=(5)2 ×2

⇒h/100 =50⇒h=5000m=5km

speed of water = 3km/hr

Time taken to fill tank =  3 /5 hr=  3 /5 ×60min=100min
