Question

A horizontal (x direction +→) water jet from a round nozzle is striking towards right on a curved vane at velocity V = 8 m/s with a flow rate of Q = 160 Liter per minute. The direction of water is turned downwards by 45° from the direction of the striking jet and exiting the vane at the same speed. Calculate the net momentum change (exit - inlet) in the direction of the striking fluid (along x direction towards right→) in newtons. Use value of the gravitational acceleration g = 9.81 m/s² and water density of 1000 kg/m³. Ensure to convert the units to correct units and use the correct sign.
