Question

Water is discharged from a pipe of cross section area 3.2$c{m}^2$ at a speed of 5m/s. Find the volume of water discharged in $c{m}^3$ per second.

• A. 1600 $c{m}^3$
• B. 1500 $c{m}^3$
• C. 160 $c{m}^3$
• D. 1000 $c{m}^3$

Answer 1

The correct option is A

1600 $c{m}^3$

Volume of water flowing = area of cross section x speed of water

Area of cross section = 3.2$c{m}^2$

Speed of water = 5m/s = 500cm/s

Volume of water flowing per second = 3.2 x 500 = 1600 $c{m}^3$
