Abstract In this project, we present the characteristic of fluid flow and some applications of inviscid flows. Inviscid fluid is a fluid in which the coefficient of viscosity is zero.Using Bernoulli’s equation and continuity equation, we determine the velocity distribution of a fluid through a pipe or a tube.By applying Bernoulli’s equation of motion in inviscid flow, the objective is to solve the motionof fluid flow through Pitot tube,Venturi meter,liquid draining from a tank,air flow along wing of an airplane,Trajectory of a free jet and gas flow inDe Laval Nozzle.
