flows through a nozzle which has inlet areas of (10 cm ^ 2) . If the air has a velocity of (120 m/s) a temperature (300K) and a pressure of (700kpaat the inlet section and a pressure of 250kpa) at the exit find the mass flow rate through the nozzle and the velocity at the exit of the nozzle, assuming one dimensional isentropic flow. (R=287 J/kg. K), (K=1.4).

Air flows through a nozzle which has inlet areas of
(10 cm2
). If the air has a velocity of (120 m/s) a
temperature (300K) and a pressure of (700kpa) at the inlet section
and a pressure of (250kpa) at the exit,
find the mass flow rate through the nozzle and the velocity at the
exit of the nozzle, assuming one-
dimensional isentropic flow. (R=287 J/kg. K), (K=1.4). (25%)

Air flows into a commercial steel pipe of 5 cm ID at 70 m/s.
The inlet pressure and temperature of the air are 1 MPa and 100?C,
respectively.
a) Determine the Mach number at a distance 60 m down the pipe
if the flow is adiabatic.
b) Calculate the temperature at the same point. How would you
comment on the assumption of
constant Re, hence constant f, along the pipe by considering
the temperature variation?

Steam in a heating system flows through tube whose outer
diameter is 10 cm and whose walls are
maintained at a temperature of 150°C. Circular aluminum alloy
2024-T6 fins (k = 186 W/m · °C)
of outer diameter 15 cm and constant thickness 2 mm are attached to
the tube. Heat is transferred
to the surrounding air at T∞ = 25°C, with a heat transfer
coefficient of 50 W/m2 C . If the total
tube length is 5 m and...

Steam flows steadily through an adiabatic turbine. The inlet
conditions of the steam are 4
MPa, 500°C and 80 m/s, and the exit conditions are 30 kPa, 92%
quality and 50 m/s. The
mass flowrate of the steam is 12 kg/s. Investigate the effect of
the turbine exit pressure on
the power output of the turbine. Let the exit pressure vary from 10
to 200 kPa. Plot (1) T2
vs P2 and 2) Plot the power output (W_dot_T in MW)...

Benzene (876.5 kg/m3) flows into a 10.3 cm diameter,
inlet pipe (a.k.a Zone 1) at a pressure of 1.948 bar. The liquid
then flows through a 6.2 cm diameter pipe at a pressure of 1.001
atm situated 1.4 m above the inlet pipe, a.k.a Zone 2.
a) Calculate the flow speed of the Benzene in
Zone 2.
b) Calculate the volume flow rate of the
Benzene in either Zone

Water (1,000 kg/m3) flows into a 10.2 cm diameter,
inlet pipe (a.k.a Zone 1) at a pressure of 1.671E5 Pa. The liquid
then flows out of a 8.7 cm diameter, open faucet situated 1.6 m
above the inlet pipe, a.k.a Zone 2.
a) Calculate the flow speed of the Water in
Zone 2.
b) Calculate the volume flow rate of the Water

Air flows steadily through a converging-diverging nozzle with a
throat area equal to 1.395 in2 , and an exit area equal to 2.79 in2
. A normal shock wave stands at the exit plane of the nozzle. The
exiting jet flows into a large room, where the pressure is equal to
14.7 psia. The temperature of the air in the exit jet stream, just
after the nozzle exit, is measured at 87 deg F. Calculate the mass
flow rate through...

Consider a diffuser in which air flows steadily. At the inlet of
the diffuser the pressure, the temperature and the velocity of the
air are 100 kPa, 110oC and 175 m/s, respectively. At the exit of
the diffuser the pressure, the velocity of the gas and the area of
the diffuser are 110 kPa, 15 m/s and 0.1 m2 , respectively.
Accounting for an heat loss of 3 kJ/kg from the diffuser to the
surroundings at 100 kPa and 25oC...
