(i) In cm3 per sec.
(ii) In liters per minute.

उत्तर
(i) The rate of speed = ` 5 "m"/s = 500 "cm"/s`
The volume of water flowing per sec = 3.2 x 500cm3 = 1600 cm3
(ii) Vol. of water flowing per min = 1600 x 60 cm3 = 96000 cm3
Since 1000 cm3 = 1 litre
Therefore, Vol. of water flowing per min= `(96000)/(1000 )` = 96 litres
