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...

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...

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

Force from a Jet of Water A jet of fluid striking a vane exerts a force on the vane it is equal and opposite to the vane. It is the equal and opposite force of the fluid momentum change that accompanies such a flow. For different weights, the water flow rate is adjusted so the platform stays at the zero reading.

A water jet with a velocity of V; -8 m/s and jet diameter D; -10 cm impinges on a cup cavity. The water is turned 180° and exits, due to friction, at lower velocity of Ve= 4 m/s. Looking from the left, the exit jet is a circular annulus of outer radius (R) and thickness (h), flowing toward the viewer. The cup has a radius of curvature of R-10cm. Find the thickness of the exit jet (h=?cm) Oh=1.0 cm h...
