A water jet "pump" has a jet area of A0 and jet speec V0. The jet is within a secondary stream of water having speed 1/10V0. The total area of the duct is 5A0. The water is completely mixed and leaves the jet pump in a uniform stream. The pressures of the jet and secondary stream are the same at the pump inlet. Determine the speed at the pump exit and the pressure drop p1-p2. Note, of course, that a similiar sitatuion could exist within an artery due to a high velocity flow through a needle or catheter.
