Water is flowing at the rate of 15km/hour through a pipe of diameter 14cm into a cuboidal pond which is 50m long and 44m wide. In what time will the level of water in the pond rise by 21cm?

Text Solution

Verified by Experts

Quantity of water flowing through pipe in 1 hour
`= pi xx (7)/(100)xx (7)/(100) xx 15000m^(3)`
Required time `= (50 xx 44 xx (21)/(100))div (pi xx (7)/(100) xx (7)/(100) xx 15000)`
= 2 hours
