Question

1. In a typical nozzle, air is used as a medium to undergo increased velocity at the exit. Air at 627 0C enters into a nozzle with negligible velocity and leaves at 27 0C. Determine the velocity of air the exit, assuming no heat loss and nozzle being horizontal. Take the value of Cp = 1.005 kJ/kg K for air. Also, determine the area of the nozzle at the exit, if the density of the air is 1.12 kg/m3.

In a typical nozzle, air is used as a medium to undergo
increased velocity at the exit. Air at 627 C enters into a nozzle
with negligible velocity and leaves at 27 C. Determine the velocity
of air the exit, assuming no heat loss and nozzle being horizontal.
Take the value of Cp = 1.005 kJ/kg K for air. Also, determine the
area of the nozzle at the exit, if the density of the air is 1.12
kg/m^3 . (you...

1. In a turbo jet engine, the momentum of the gases
leaving the nozzle produces the propulsive force. The enthalpy and
velocity of the gases at the nozzle entrance are 1200 kJ/kg and 200
m/s respectively. The enthalpy of the gas at exit is 900 kJ/kg. If
the heat loss from the nozzle is negligible, determine the velocity
of the gas jet at exit from the nozzle.
2. For question 1, if the diameter of the nozzle at
exit is...

1) A nozzle is a device for increasing the velocity of a
steadily flowing stream of fluid. At the inlet to a certain nozzle
the enthalpy of the fluid is 3025 kJ/kg and the velocity is 60 m/s.
At the exit from the nozzle the enthalpy is 2790 kJ/kg. The nozzle
is horizontal and there is negligible heat loss from
it.
(i) Find the velocity at the nozzle exit.
(ii) If the inlet area is 0.1 m2 and specific volume...

Air at 790kPa, 573oC and 8m/s enters an adiabatic
nozzle at a rate of 1.95kg/s and leaves at 101oC and
177kPa pressure. If the nozzle is placed horizontal hence the inlet
and outlet are at the same height, determine the exit velocity of
the air (m/s). Assume the cp air = 1.005kJ/kg.K.

Steam enters a converging-diverging nozzle at steady state with
P1 = 40bar T1 = 400°C and a velocity of
12m/s. The steam flows through the nozzle with negligible heat
transfer and no significant change in potential energy. At the exit
P2 = 15bar and the velocity is 700 m/s. The mass flow
rate is 2.5 kg/s. Determine the exit area of the nozzle in
m2

1. Air enters a converging-diverging
nozzle with a total pressure of 1100 kPa and a total temperature of
127°C. The exit area to throat area ratio is 1.8. The throat area
is 5 cm2. The velocity at the throat is sonic and the
diverging section acts as a nozzle. The diverging section is now
acts as a supersonic nozzle. Assume that a normal shock stands in
the exit plane of the nozzle. Determine the following:
a. The static pressure and...

A jet engine is operating at an altitude of 7000 m. The mass of
air passing through the engine is 46 kg/s and the heat addition in
the combustion chamber is 500 kJ/kg. The cross-sectional area of
the combustion chamber is 0.5 m2, and the air enters the chamber at
a pressure of 80 kPa and a temperature of 80°C. After the
combustion chamber, the products of combustion, which can be
assumed to have the properties of air, are expanded...
