A 6-cm-diameter vertical water jet is injected upward by a nozzle at a speed of 15 m/s. Determine the maximum weight of a flat plate that can be supported by this water jet at a height of 2 m from the nozzle. Take the density of water to be 1000 kg/m3 The maximum weight of a flat plate that can be supported by the water jet is 52475 N. KPrev 8 of 8N
Objective To determine the force generated by a jet of water striking on a surface Description of apparatus The supply is led to a vertical pipe terminating in a tapered nozzle. This produces a jet of water which impinges on the vane in the form of a Flat Plate, Hemispherical Cup, Conical Plate or 30° Angled Plate. The nozzle and vane are contained within a transparent cylinder; at the base of the cylinder there is an outlet by which 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...
1. Falling Ball with Air Resistance (15 points) A round bal is dropped from a height for which air resistance is not negligible by the time the ball hits the ground A. On what dimensional parameters does the ball's impact speed depend? Define al symbols and give their dimensions B. Show at least three different ways that the impact speed may be made dimensionless C. On what dimensionless parameter(s) does the dimensionless speed depend? 2. Laminar Jet Toward Plate (15...
Please solve both with showing steps 5.29. A 4.0-cm diameter nozzle delivers a jet of water that strikes a flat plate normally. If the water speed is 50.0 m/s, calculate the force acting on the plate if (a) the plate is stationary. 5.32. A 4-in-diameter nozzle is fitted at the end of a 10-in diameter pipeline, as shown in Figure P5.32. The pressure at the end of the pipe (nozzle inlet) is 20 psi and at the nozzle exit the...
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,...
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. These values are given below Q, ftA3/s 0045 0069 0011 0107 0116 0041 0076 0113 0146 Weight Angle, deg...
Name:AbalYauni Test 03Show Your Work EGR 212 31 One of the most advanced methods for cutting metal plates uses a high-velocity water jet which carries an abrasive garnet powder. The jet issues from the 0.01-in.-diameter nozzle at A and follows the path shown through the thickness t of the plate. As the plate is slowly moved to the right, the jet makes a nar- row precision slot in the plate. The water-abrasive mixture is used at the low rate of...
A 2.8-kg disk is constrained horizontally but is free to move vertically. The disk is struck from below by a vertical jet of water. The speed and diameter of the water jet are 12 m/s and 25 mm at the nozzle exit. (a) Obtain a general expression for the speed of the water jet as a function of height, h. (b) Find the height to which the disk will rise and remain stationary. M = 2.8 kg d=25 mm A...
