A convergent - divergent nozzle receives wet steam of 2% wet at a pressure of 26 bar with an approach velocity of 100m/ S and expands it to a back pressure of 0.3 bar. Nozzle efficiency is 85% and all the frictional losses take place in the divergent portion only. Determine: (a) The critical throat pressure (b) The discharge of steam (c) The area of cross section of the nozzle at its exit.
The refrigerant R134a is passing through the diffuser with the inlet diameter of D1=1 inch; p1=150psi; and V1=1000 ft/s as a saturated vapor. The exit parameters are p2=400 psi, and velocity V2=0.5 ft/s. Heat transfer, Work, and Potential energy changes can be neglected. NOTE: Use English units. For the kinetic energy change do not forget dividing to (778*32.2) conversion factor to obtain Btu/lbm. From NIST tables use BTU/lbm units for the enthalpy. Determine: a.Exit temperature in F; b.Mass flow rate in lbm/s; c.Exit diameter D2 in inches. d.Determine exit temperature.

What is the pressure drop in the turbine? Answer: 1176.91 kPa (replace “turbine pressure drop” for “pump pressure increase”)
In a trial run, the De Laval steam turbine at Oman Power Plant rotates at 3000 rpm. The steam is issued from the nozzle at 400 m/s and the nozzle angle is 20o. The blade speed ratio is 0.41and the friction loss in the blade channel is 15%of the kinetic energy corresponding to the relative velocity at the inlet to the blades. As a turbine engineer at that station, how do you determine the (i) power developed by the turbine for a flow rate of 10 kg/s and (ii) suitable inlet and outlet angles for the blades when axial thrust is zero. Also, how would you determine the size of the turbine wheel required? Draw a suitable velocity diagram.
14A fluid flows at a speed of 7.5 m/s in a pipe with a diameter of 35 cm. What is the power, in W, of the pump to overcome the irreversible pressure drop when the pressure drop along the pipe is calculated to be 6300 Pa?
A turbine of 9000 B.H.P. is working under a head of 25 mand runs at 100 R.P.M.- What will be the type of turbine ? Whatshould be its speed and power, when it is working under a head of16 m?
Air enters a fan through a duct velocity of 6.3 m/s and an inlet static pressure of 2.5cm of water less than the atmospheric pressure. The air leaves the fan through the duct at a velocity of 11.25 m/s and a discharge pressure of 7.62cm of water above the atmospheric pressure. If, the density of the air is 1.2kg/m3and the fan delivers 9.45m3/s, what is the fan efficiency when the power input to the fan is 13.75 kW at the coupling. Show schematic diagram and provide solutions.
The nozzle angle for an axial flow impulse turbine is 15°. The inlet absolutevelocity is 800 ft./s and the blade speed is 550 ft./s. Axial speed at the inlet andoutlet is assumed to be a constant. Calculate (a) energy transfer E, (b) change intotal (stagnation) and static enthalpies, (c) utilization factor.Ans: E=∆h0=245,038 ft-lbf/slug; ∆h=0; ε=0.77
Using the situation below, how would I determine the net resultant force exerted on the reducer by the water? In this situation, water is flowing horizontally in a pipe that has a diameter of 25cm. This water is flowing at 8 m/s and at 300 kPa gage it enters a 90 degree bend reducing section. This bend reducing section is connected to a vertical pipe that has a diamater of 15cm. Moreover, the inlet of the bend is 45 cm above the exit. Here, fricition and gravity are negligible and the momentum flux correction factor is 1.04.
Toluene at 35 degrees Celsius is pumped from an open reservoir to a tank kept at a gauge pressure of 150 kPa. The pump itself is 3m below the reservoir, while the discharge tank is 10m above the reservoir. Assuming friction in the suction line is negligible, while in the discharge line the friction head amounts to 7.5 m, determine the net positive suction head available for the pump. If the pump has an efficiency of 65%, determine the total power input. At the given temperature, the density and vapor pressure of toluene are 862 kg/m3 and 40 mmHg
