Fluid flows through a converging duct as shown in the figure below. Cross-sectional area of the duct varies as given by the relation A = Ao(1 – bx), where x is measured from the inlet, Ao is the cross-sectional area of the duct at the inlet and b is a constant. The free stream velocity is given by u = c(1+ at), where c and a are dimensional constant. The expression for acceleration assuming inviscid flow & no accumulation within the duct, is given by cb(1+at)] (1-bx)?
