Question 2 (6 marks) A vane with an angle of 30° is attached to a cart (Figure 2). The cart and vane (mass of 75 kg) move on a level track with a constant speed of 10 m/s. The vane receives a jet of water (p = 1000 kg/m) that leaves a stationary nozzle with speed of 35 m/s. The nozzle exit area is 0.003 m². Assume that this cross-sectional area of the water stream does not change as it...

a 50-mm-diameter jet of water impacts a vane at a
velocity of 20 m/s as shown in Figure 4.78. The vane has a mass of
90 kg, and it deflects the jet through a 55° angle. The vane is
constrained to move in the direction of the incoming jet, and there
is no force opposing the motion of the vane. Determine the
acceleration of the vane when it was first released. Assume water

Problem 15.125
Water is discharged from a nozzle with a velocity of 8 m/s and
strikes the blade mounted on the 18-kg cart. The nozzle has a
diameter of 50 mm and the density of water is ρw = 1000 kg/mg3.
A: Determine the tension developed in the cord, needed to hold
the cart stationary.
B: Determine the normal reaction of the wheels on the cart.

Q3. The jet of water having a cross-sectional area of 2 x 10-m² and a velocity of 45 m/s strikes the vane of a turbine, causing it to move at 20 m/s. Determine (a) the dynamic force (Fx & Fy) of the water on the vane [15 points]; (b) the anchoring force (Fx & Fy) required to hold the vane stationary [15 points). Neglect the weight of water and vane for simplicity. Hint: pwater = 1000 kg/m, Assume VA =...

A water jet strikes a vane and exerts a force on it. This force
is balanced by the weight W. The purpose of this experiment is to
compare the theoretical force on the vane with the experimentally
measured force. The experiment is as follows:
We measure the outlet diameter, d, of the nozzle. Then, we
fasten θ=90o ? vane to its support and adjust the balance spring to
give a zero reading when there is no weight, W, on the...

1 (a) A steady stream of water jet discharges from the nozzle with a uniform velocity of 10 m/s at angle 60° as shown in Figure 1. The jet strikes a horizontal plate 2 m above the nozzle exit. Upon impact, part of the flow is guided towards the left while the remainder towards the right, and the plate is suspended in the air. The weight of the plate is 25 N. Assume frictionless flow along the plate and weight...
