1. Consider a water jet having a diameter of D = 1 cm and a flow of Q = 1 L/s. The jet is deflected by a fixed plate which is inclined at an angle of 50° from horizontal. a) Determine the velocity vx in the x-direction in m/s. b) Determine the velocity vy in the y-direction in m/s. c) Determine the resultant force Fx on the plate in the x-direction in N. d) Determine the resultant force Fy on the plate in the y-direction in N. e) Determine the combined resultant force F on the plate in N. 1 L/s 50° V = 6 m/s
The block slides at a constant speed on a surface with friction. In each case, the water jet has velocity 50 m/s and cross-sectional area 5 cm2, and the block has velocity 25 m/s. In case (a), the jet is deflected to an angle of 60° from horizontal relative to the block, as shown. In case (b), the jet is deflected 180°. Calculate the friction force in each case. Apply both a moving Reference Frame (RF) and a fixed RF. Use the VSM. Check that both RFs give the same friction force for a given case. (We would not expect the two cases to have the same friction force!) Density of water is 1000 kg/m3. All jets are open to the atmosphere. case (a) 60° case (b)
