Problem 2. An engineer helps with the design of a rotating spray for a dishwasher. The spray has 4 identical jets spaced equally around the rim of a disc. Water enters though a hollow shaft and then flows radially out to the jets. The nozzle of the jet has a diameter D of 0.3 cm and makes an angle a = I (3 with the horizontal plane of the disc(See figure). The jets are oriented so that v2r=0. If the total flowrate Q=50 mL/s and the disc has radius R= 7.5 cm, determine the torque in dyne-cm required to keep the disc from rotating. Water jet R. Water flows radially inside dise to jet Water in View from top View from side
A single-stage axial flow pump with outer radius r2 =0.240 m and inner radius r1 =0.120 m is given. At a radius of r =0.090 m, absolute flow flows in from the axial direction just before the impeller inlet and relative flow flows out in the axial direction just after the impeller outlet. Assuming a flow rate Q = 0.265 m^3/s, a water density ρ = 1.000 × 103 kg/m^3, a rotation speed n = 2.4 × 10^3 rpm, and a gravitational acceleration g = 9.81 m/s^2 , and assuming that the theoretical head Hth = W/g (W: specific work) derived from Euler's law is constant at all impeller radii, answer the following questions. (1) Find the velocity triangles just before the impeller inlet and just after the impeller outlet at a radius of r =0.09 m.
The jet of water of a pelton wheel is 80mm diameter. The jet strike's the bucket on the tangential line 0.45m from the centre of the wheel and the jet is deflected through 160° while it is moving across the bucket. Ignore friction and determine the power and hydraulic efficiency if the speed is 275 r/min and the pressure behind the nozzle is 680kPa
Complete Solution please, thanks. 3. A vertical circular stack 30 m high converges uniformly from a diameter of 6 m at the bottom and 4.5 m at the top. Gas with a unit weight of 0.12 N per cubic meter enters the bottom of the tank with a uniform velocity of-assume values with decimals between 3 to 4 m per second- enters the stack. The unit weight increases by 7.5 percent every 2 meters. Find the velocity of flow at every 5 meters along the stack.
Problem 14.2 A jet of water (r = 1000 kg/m³) is deflected by a vane mounted on a cart. The water jet has a constant cross-sectional area, A = 50 cm², which is projected off the vane at an angle q = 30° with respect to the horizontal. The pressure everywhere within the jet is atmospheric. The incoming jet velocity (with respect to the ground) is Vjet = 4.5 m/s. The cart has mass 50kg. Determine: a. the forces, Fx and Fy required to hold the cart stationary Vjet Vcart Fy Fx b. the horizontal force component, Fx, if the cart moves to the right at the constant velocity, Vcart = 3 m/s c. the horizontal acceleration of the cart at the instant when the cart moves with velocity Vcart = 2.5 m/s if no horizontal forces are applied Ans: a) 10 N
A storm drain has a maximum capacity of 120 L/min. During heavy rains, an influx of 240 L/min approaches the drain. Assuming the drain is cylindrical, by how much would the drain radius need to be increased to handle the heavier rainfall? Assume the water travels at the same linear speed in both drains. The answer is 1.4. Please explain why A 16 times greater B 42 times greater C 2 times greater D 1.4 times greater
A high-pressure washing system's pump supplies 1 gallon of water persecond at 100 psi pressure. The nozzle should be designed so that the static pressureof the water as it exits the nozzle is the same as the atmospheric pressure. If theinside diameter of the hose leading from the pump to the nozzle is 2 in., whatshould the diameter of the nozzle exit be? What will be the velocity of the waterat the exit of the nozzle?
