A straight horizontal pipe 100 mm in diameter terminates in a short, tapering nozzle from which a jet of water 50 mm in diameter is discharged to atmosphere. If the gauge pressure immediately before the nozzle is 50 kPa and friction in the nozzle is negligible, calculate the tensile force between the nozzle

A jet of water impinges on a single smooth flat vane at its centre. The velocity of the jet is 70 m/s and the diameter 120 mm.Calculate the force on the vane, if it is moving with a velocity of 30 m/s in the direction of jet. Determine the power and efficiency. Also, find the speed of plate at which maximum efficiency may occur.

The diameter of a pipe changes gradually from 75 mm at a point A, 6 m above datum, to 150 mm at B, 3 m above datum. The pressure at A is 103 kPa and the velocity of flow is 3.6 m/s. Neglecting losses, with the aid of a neat sketch, determine the pressure at B

The diameter of a pipeline is 6-in at A and 18-in at B. A is 11 ft. lower than B. If the pressure at A is 10 lb per sq. in and at B 7 lb per sq. in when the flow is 2.5 cfs, determine the frictional loss between A and B when the liquid is water. Topic: FUNDAMENTALS OF FLUID FLOW

Q5: A converging-diverging nozzle, which is shown in the figure, is supplied with air from a large tank where the pressure is Po and exhausts to the atmosphere with a pressure of Po. The area A at distance x from the throat is given by (A = At (1 + 0.75x/L)), where At is the throat cross- sectional area and Lis the total length of the diverging part of the nozzle. At a certain pressure ratio PoPb, a normal shock wave stands in the nozzle at a point where the Mach number before the shock is 1.7. Find the position of the normal shock wave from the throat, and the pressure ratio P/Po. Ans.: 0.45 L = 0.753 Р. Ps

Q1. What would be the effect on the calculated force on the flat plate if the jet were to leave the plate not horizontal but inclined upwards at an angle of 1 °? If the experiment were to be repeated with the vane in the form of a cone with an included angle of 60° (half angle 30°), how would you expect the results to appear?

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?

3. A horizontal nozzle reduces from 100 mm bore diameter at inlet to 50 mm at exit. It carries liquid of density 1000 kg/m3 at a rate of 0.05 m3/s. The pressure at the wide end is 500 kPa (gauge). Calculate the pressure at the narrow end neglecting friction. (196 kPa)

Water steam is running through the nozzle. Inlet pressure is P1=25 bars; T1=300C; V1=90m/s; A1=0.2m2. The exit parameters are: P2=11bars; T2=210C. The mass flow rate is m=2 kg/s. Determine: a.Exit velocity V2=?; b.Inlet and outlet diameters D1 and D2.
