1.	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?
Answer» Quantity of water flowing through pipe in 1 hour = (π x 7/100 x 7/100 x 15000 m³) Required time = (50 x 44 x 21/100) ÷ (π x 7/100 x 7/100 x 15000) = 2 hours

Answer»

Quantity of water flowing through pipe in 1 hour

= (π x 7/100 x 7/100 x 15000 m³)

Required time = (50 x 44 x 21/100) ÷ (π x 7/100 x 7/100 x 15000)

= 2 hours
