4. A converging nozzle is fed with air from a large reservoir where the. pressure and temperature are 250 kPa and 300 K, respectively. If the nozzle discharges to a region where the pressure is 100 kPa, determine the pressure and cross-sectional area at the exit of the nozzle. Assume that the flow is reversible and adiabatic with a mass flow rate of 10 kg-s. (100 kPa, 0.01714 m?)

section and the mass flow rate per unit area.
(Ans: 0.46, 103.3 kg-s'm).
3. A converging nozzle is fed with air from a
large reservoir where the temperature and
pressure are 400 K and 170 kPa, respectively.
The nozzle has an exit cross-sectional area of
0.001 m? and discharges into the atmosphere
with a pressure of 100 kPa. The flow is
isentropic throughout the nozzle. Determine
the pressure, Mach number, temperature and
velocity at the exit plane, and also find the
mass flow rate. (Ans: 100 kPa, 0.9, 344.8 K,
334.8 m-s", 0.3388 kg-s").

5. Air is supplied to a converging nozzle from a
large reservoir, where the pressure and
temperature are kept constant at 500 kPa and
300 K, respectively. If the nozzle discharges to
the atmosphere with a pressure of 100 kPa,
find the time required to discharge 2 kg of air.
The exit area of the nozzle is 10 cm". Assume
isentropic flow. (Ans: 1.714 s)
