Water is flowing at the rate of 5 km/hour through a pipe of diameter 14 cm into a rectangular tank, which is 50 m long and 44 m wide. Determine the time in which the level of water the tank will rise by 7 cm.

Text Solution

Verified by Experts

`volume of tank = 50xx44xx7/100`
`=(22xx7)m^3`
volume of pipe `= 5xx5/18xx22/7xx7/100xx7/100xxT`
`=25/18xx(27xx7T)/(10000)m^3`
volume of tank= volume of water in pipe``
`22xx7=25/18xx(22xx7xxT)/10000`
`T=(18xx10000)/25`
`T=7200 sec`
