Question No: 03 This is a subjective question, hence you have to write your answer in the Text-Field given below. ructions Options Help Center An orifice is to be used to indicate the flow rate of water in a 15 cm diameter line at room conditions. The orifice diameter is 6 cm. What pressure reading will be experienced on the orifice for a line-flow velocity of 15 m/s? What would be the flow rate for a pressure reading of twice this value?
Sometimes the simplest things in nature exhibit a stunning and elegant beauty. Consider the slow running faucet in the picture below. You've probably seen many times how the column of water is thinner at the bottom than at the top. Today, we will analyze this beautiful image. Velocity = V1 Radius = r1 y%3y1 Velocity = v, Radius = r2 V2=0 Both location 1 and location 2 in the figure are outside the faucet and the water is in contact with air at both places. The top (starting) location is at a height y, = 0.26 meters and the end location is y2 = 0. At the top location, the water has a velocity %3D V, = 2.00 m/s and the stream of water has a radius of r; = 0.011 meters. Use your knowledge of fluids to determine all the following: The volume rate of flow leaving the faucet: m³/sec The velocity of the fluid at location 2: V2 = m/s The radius of the fluid stream at location 2: r2 = meters NOTE: You will not need pressure or density to solve this problem.
Example (1-3): A jet of water 8 cm in diameter moving with velocity of 12 m/s strikes a flat vane which is normal to the axis of the stream. (a) Find the force exerted by the jet if the vane moves with a velocity of 5 m/s. (b) Determine the force exerted by the jet if instead of one flat vane, there is a series of vanes so arranged that each vane appears successively before the jet in the same position and always moving with a velocity of 5 m/s. (c) Determine also the efficiency of the system.
In the figure the V-shaped pipe is filled with water, it is desired that the liquid remains in the tube and not spilled. At what angular velocity can we rotate the axis of symmetry of the tube so that water does not spill when the plug is opened.
Fluid Mechanics. Fluid kinematics. The figure below represents the upper view of pillars, with circular sections of 0.5 m, which support a bridge. The figure also shows the river speeds before and after reaching the pillars.

n undergraduate student of mechanical engineering wishes to calculate the fow rate through the pipe shown in Fig. 5. He applies Bernoulli's equation (mechanical energy equation) between point 1 and 2, and obtains an expression for the velocity (V) in the pipe as below, V = 2gHD fL What is the fallacy in his argument and what should be the correct expression for V? At approximately what L/D ratio would you expect the above equation to give results within, say one percent of the correct value (use Darcy's friction factor f = 0.02) 1 H water D 2
A constant area pipe filled with running water runs downhill then back up hill: O Why would anybody make a pipe go downhill then back uphill – what a waste of pipe! The dynamic pressure remains constant but only if there are no energy losses The dynamic pressure remains constant even if there are energy losses O The total pressure remains the same irrespective of any energy losses The dynamic pressure increases then reduces
A jet engine on a test stand directs a stream of hot exhaust gasses against a vemcal wall. All of the exhaust gas leaving the wall after impact is in the y-z plane (ie no "x" direction velocity). The mass rate is 200 kg/s and the velocity is 400 m/s. (Note that the density and viscosity are not relevant) What is the force on the wall (include direction)?
A pressurized tank of water is used to create a fountain, as illustrated. Assume that the water's free surface area in the tank is very large relative to the pipe's cross-sectional area, which is circu- lar with diameter d 1.0 cm. The small pipe bend has height = 10.0 cm. At the instant when 0.75 m, H = 2.5 m, and the gauge measures a pressure of Pgauge 20.0 kPa, the water spray reaches a height L above the pipe exit. h = = = Neglecting viscous effects, determine the height of the spray, L.
