Answer
(i) Cross-sectional area = 3.2 cm2
Speed of water = 5 m/s = 500 cm/s
Volume of water discharged per second = Cross-sectional area x Speed
= 3.2 x 500
= 1,600
Hence, the volume of water discharged per second is 1600 cm3.
(ii) Volume of water discharged per min = 1600 x 60
= 96,000 cm3
= = 96 litres
Hence, the volume of water discharged per minute is 96 litres.
