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» Solution :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 |
