A 0.20 kg ball is held stationary by a jet of water from falling. At the nozzle, the speed of the jet is 5m/s, and its diameter is 10mm. Find the velocity at which the water jet hits the ball and the height of the ball. Density of water is 1000kg/m2. Assume there is no change in the diameter of the water jet. 2.1 Find the velocity of the jet as it hits the ball (hint: the weight of the...
Problem 6.031 A cone that is held stable by a wire is free to move in the vertical direction and has a jet of water (at 10°C) striking it from below. The cone weighs 30 N. The initial speed of the jet as it comes from the orifice is 35 m/s, and the initial jet diameter is 2 cm. Find the height to which the cone will rise and remain stationary. Note: The wire is only for stability and should...
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...
Problem 6.057 A spray system is shown in the diagram. Water is supplied at p, through the flanged opening of area A 3 in.2 The water leaves in a steady free jet at atmospheric pressure. The jet area and speed are a 1.3 in.2 and V 16 ft/s. The mass of the spray system is 0.2 lbm and it contains 12 in.3 of water.An object, with a flat horizontal lower surface, moves downward into the jet of the spray system...
Notre Dame University Faculty of Engineering seawater jet hits a tank aluminum (p 280o kg/m3) that is subme attached through a pulley system to a cylindrical solid block of s submerged in a pool of sea water as shown in Figure P The diar-stance between the eseawaterjet is A = 0.15m2 and θ-70". The coefficient of 1. l area of the n the wheels of the cart and the ground is assumed to be equal to 0.04. num block is...
A large water fountain pump floats in water and is held by a rigid horizontal rod as shown in Fig. 3 The pump produces a cylindrical water jet at 609. The jet exhausts to the atmosphere at atmospheric pressure and originates from the pumping device that accelerates the flow from zero velocity inside the pump Volume. The flow rate of the jet is 1 and its diameter is 2/Vĩm. You can ignore frictional losses, the gravitational forces in the jet,...
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
