A pipe of non uniform cross section has two distinct section ` 1` and `2 ` with areas `2cm^(2)` and `4cm^(2)` respectively. If the velocity of flowing liquid at section `1` is `5cm//s`, determine the velocity at section `2`. |

Answer» From the equation of continuity `a_(1)v_(1)=a_(2)v_(2)` Given `a_(1)=2cm^(2),a_(2)=4cm^(2),v_(1)=5cm//s, v_(2)=?` `:. 2(5)=4(v_(2))impliesv_(2)=2.5cm//s` |
