The diameter of nozzle The volumetric flow rate of a fluid from the nozzle The density of the fluid Jet deflection angle The diameter of the reaction vaneThe diameter of the reaction vaneLab 5 Which of the following assumptions is not made to simplify the momentum equation for calculating the impact force? (Hint : watch the video lecture) The deflection angle of the water jet after striking the impact surface is greater than 90 degrees. There is no friction between the water and the impact surface. The velocity of the water jet remains constant before and after striking the impact surface. The fluid velocity is uniform over its cross section when it enters and leaves the control volume. The areas entering and leaving the control volume are equal to the area of the nozzle.The deflection angle of the water jet after striking the impact surface is greater than 90 degrees.Lab 5 T/F As the volumetric flow rate through the nozzle increases, the impact force of jet also increases.True
