Helium at 200 kPa, 227 C is expanded in steady flow through a nozzle to 100 kPa. At these operating conditions the nozzle efficiency is 76%.

a) Making the usual nozzle assumptions, calculate the actual velocity at the nozzle exit. Start with the appropriate form of the first law.

b) Calculate the actual nozzle exit temperature.

Air passes through a jet engine nozzle operating at steady state. The flow at the nozzle inlet has a temperature of 900° F. The nozzle inlet has an area of 5 ft2. The flow at the nozzle outlet has a temperature of 875° F, a specific volume of 90 ft3/lb, and a velocity of 600 ft/s. The nozzle outlet has an area of 2 ft2. Model the air as an ideal gas with constant specific heats. Evaluate the specific heats...

At steady state, air at 200 kPa, 330 K, and mass flow rate of 0.5 kg/s enters an insulated duct having differing inlet and exit cross-sectional areas. The inlet cross-sectional area is 6 cm2. At the duct exit, the pressure of the air is 100 kPa and the velocity is 250 m/s. Neglecting potential energy effects and modeling air as an ideal gas with constant cp = 1.008 kJ/kg · K, determine: (a) the velocity of the air at the...

Air is supplied to a convergent–divergent nozzle from a reservoir where the pressure is 100 kPa. The air is then discharged through a short pipe into another reservoir where the pressure can be varied. The cross-sectional area of the pipe is twice the area of the throat of the nozzle. Friction and heat transfer may be neglected throughout the flow. If the discharge pipe has constant cross-sectional area, determine the range of static pressure in the pipe for which a...

Consider the steady, incompressible blood flow through the following vascular network: 100 µm diameter which is 80 mm in length to the first branching point, which can be estimated as a standard tee (flow through run), the branch off the tee turns 45 degrees and undergoes a constriction to 65 µm diameter and the flow through run continues for another 80 mm. The velocity of the blood into the 100 µm diameter vessel is 100 mm/s and 20% of the...
