#### Question

Water in a rectangular reservoir having base 80 m by 60 m i s 6.5 m deep. In what time can the water be emptied by a pipe ôf which the cross-section is a square of side 20 cm, if the water runs through the pipe at the rate of 15 km/hr.

#### Solution

Given that,

Flow of water = 15km / hr

=15000m/hr.

Volume of water coming out of the pipe in one hour

`20/100xx20/100xx± 5000=600m^3`

`"Volume of the tank"= 80xx60xx6.5`

`=31200m^3`

∴Time taken to empty the tank

`="Volume of tank"/"volume of water coming out of the pipe in one hour"`

`=31200m^3`

`=52 hours.`

Is there an error in this question or solution?
