constant velocity of 3 m/s?[ Note: Neglect the pressure force effects] DA 7.6 cm jet of water strikes a vertical plate in its centroid. Find the velocity of water through the jet if a horizontal force of 44.5 N is applied to: 1) hold the platte stationary. 2) move the plate to the right by a nir

Consider a column of water as it falls from a faucet. The opening in the faucet has radius ro and the water comes out with initial velocity vo. Define y to be the distance below the faucet. As the water falls (y increases), it accelerates due to gravity and the stream narrows. a) Assuming streamline flow, find an expression for the velocity of the water for any distance below the faucet. b) The stream obeys the continuity equation. Use this to determine the radius of the stream as a function of y. c) At what distance ₁/2 will the radius of the stream be half its original radius? At what distance Y1/3 will it be a third? d) Compare 1/2 and Y1/3 for v0 = = 1 m/s and v0 = 0.1 m/s (use g = 10 m/s²).

Q2. A 40 mm diameter jet has a velocity of 25 m/s. Calculate the resultant force on a large flat plate if this jet were to strike it normally.

Water enters a fountain through a pipe with a cross-sectional area A₁ at a flowrate Q. The pressure in the inlet pipe is p₁. The water then leaves through a nozzle with a cross- sectional area A₂ and at an angle 0, as shown in Figure Q5. Both the inlet and the nozzle are at a height h₂, and the jet reaches a maximum height h3. You may assume that viscosity is negligible. a) Find the horizontal force on the block b) What is the horizontal-component (u₂), vertical component (v₂) and magnitude (V₂) of the velocity of the jet as it leaves the nozzle? c) What is the maximum height of the jet? You may assume that the horiztonal component of velocity is the same at every point in the jet. P₁ A₂. Ө h₂ h3 Figure Q5: Jet emitting from a fountain.

Subject : Mechanical engineering ,Fluid mechanics. Question: A stream of water 75 mm in diameter discharges into the atmosphere at a velocity 24.4 m/s. Find the power in the jet using the datum plane through the center of the jet. Answer is 33 kW

You wish to water your garden with 100 ft of 5/8-in-diameterhose whose roughness is 0.011 in. What will be the delivery,in ft3/s, if the gage pressure at the faucet is 60 lbf/in2?If there is no nozzle (just an open hose exit), what is thethe maximum horizontal distance the exit jet will carry?
