Hydraulics and Fluid Mechanics in ME The length AB of a pipe ABC in which the liquid is flowing has diameter (d1) and is suddenly enlarged to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden enlargement is (v₁ - v₂)²/2g (v₁ - v₂)²/g (v₁² - v₂²)/g (v₁² - v₂²)/2g (v₁ - v₂)²/2g (v₁ - v₂)²/g (v₁² - v₂²)/g (v₁² - v₂²)/2g ANSWER DOWNLOAD EXAMIANS APP
