CONFIDENTIAL In a Dubai seashore area, there is a car wash shop Ilot that provide car washing using authentic seawater (SG = 1.029). During the car washing, the car washer injects a stream of water jet from the nozzle onto the car window (ideally modelled as a vertical plane) at a contact angle of 25. From a nozzle with a diameter of 200 mm, the water jet is issued at a very high flow rate of 0.35 m/s, so any gravity effects of water jet are reasonably to be assumed as negligible. Water jet flows in the atmosphere before striking the vertical car window, but subsequently being deflected by the car window in such a way that the water flows to the left. V2 -F, Fp X+ V1 25 Wjet F (a) Calculate the density of seawater. (1 Mark) (b) Compute the velocity at point 1 and 2. Then, identify the magnitude and direction of resolved components of all velocities. (4 Marks) (c) Identify the pressure at point 1 and 2. Then, identify the magnitude and direction of resolved components of all pressure forces. (2 Marks) (d) Identify the weight of water jet. Identify magnitude and direction of resolved components of all weight. (2 Marks) (e) Calculate the magnitude and the direction of reaction force that exerted by the car window on the water jet. (8 Marks) (f) Sketch the force diagram of reaction force that exerted by the car window on the water jet. (3 Marks)
