A horizontal nozzle of 30 mm diameter discharges a steady jet of water into the atmosphere at a rate of 15 litre per second. The diameter of inlet to the nozzle is 100 mm. The jet impinges normal to a flat stationary plate held close to the nozzle end. Neglecting air friction and considering the density of water as 1000 kg/m³, the force exerted by the jet (in N) on the plate is -

The 275-kg circular craft is suspended 100 mm from the ground. For this to occur, air is drawn in at 18 m/s through the 200-mm-diameter intake and discharged to the ground as shown. Take Pu = 1.22 kg/m³. Assume the fluid is an ideal fluid, that is, incompressible and frictionless. (Figure 1) -1.5 m -1.5 m -200 mm B 100 mm Determine the pressure that the craft exerts on the ground. Express your answer to three significant figures and include the appropriate units.

Fluid Mechanics.   Reg.no : 5393   Pb # 3: Refer to Figure 2. Assume that friction is negligible, that θ = 115o, and that the water jet has a velocity of (Reg.No/100) m/s and a diameter of 60 mm. Find (a) the component of the force acting on the blade in the direction of the jet; (b) the force component normal to the jet; and (c) the magnitude and direction of the resultant force exerted on the blade.    Note: Assume reasonable values for any missing data. Symbols have usual meaning unless otherwise stated.

For the open tank, the piezometers attached on the side, containing two different immiscible liquids, as shown in the figure, find the elevation of the liquid surface in piezometer A.

The thrust of a shaft is taken by a collar bearing filled with a forced lubrication system which maintains a film of oil of constant thickness 0.3 mm between the surface of the collar and the bearing. The outer and inner diameters of the collar are 156 mm and 120 mm respectively. The coefficient of viscosity of the oil is 1.2 poise. Calculate the power lost in friction of the bearing when the shaft rotates at 500 revolutions per minute.

2. The 600 mm pipe shown in the figure conducts water from a reservoir A to a pressure turbine, which discharge through another 600 mm pipe into water tank B. The head loss from A to 1 is 5 times the velocity head in the pipe and the head loss from 2 to B is 0.2 times the velocity head in the pipe. If the discharge is 700 L/s, what horse power is being given up by the water to the turbine and what are the pressure heads at 1 and 2 2 HE = 49.20 m HP = 453.50 hp (input) P₁/y = 53.63 m P2/y = -4.43 m A WS El 60 m EL 4.5 m 600 mm 600 mm US 90 kPa EL 0 m

Air in a room at T0 = 290 K and P0 = 90 kPa is to be drawn by a vacuum pump through a 3-cm-diameter, 2-m-long adiabatic tube equipped with a converging nozzle at the inlet. The flow in the nozzle section can be approximated as isentropic. The static pressure is measured to be 87 kPa at the tube inlet and 55 kPa at the tube exit. Determine the mass flow rate of air through the duct, the air velocity at the duct exit, and the average friction factor for the duct.
