Question 3 (Marks 30) Find the force exerted on the wall by the jet ignoring the gravity and viscous forces. 0.4-m 0.2-m diameter diameter Vi = 20 m/s V2-20m/s 0.1 m So, you considered only the incoming force in the x- direction. You need to consider the momentum change that is outgoing in the x-direction through the 0.2 m diameter section also. If you do that, you will get the right answer. Boht velocities are in the positive x-direction, so you can subtract (Momentum)out - (momentum)in = rho*Aout*Vout^2 - rho*Ain*Vin^2
