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 contracted to diameter (d2) at B which is constant for the length BC. The loss of head due to sudden contraction, assuming coefficient of contraction as 0.62, is 0.375 v₂²/2g v₂²/2g v₁²/2g 0.5 v₁²/2g 0.375 v₂²/2g v₂²/2g v₁²/2g 0.5 v₁²/2g ANSWER DOWNLOAD EXAMIANS APP
