An aircraft has a jet engine mounted on a pylon. the flight velocity is u1= 300m/s. the fully expanded velocity of the jet exhaust is uj= 800m/s. the mass flow rate through the engine is 10 kg/s (neglecting the combustion products). the static pressure at the nozzle exit is 80 kpa. the static pressure at the inlet is 20 kpa. an ambient pressure is measured as p1= 20kpa. the nozzle exit area is 4.0 m^2. determine the thrust via reynolds transport theory.

the equation above shows how temperature f, measured in degrees fahrenheit, relates to a temperature c, measured in degrees celsius. based on the equation, which of the following must be true?

a temperature increase of 1 degree fahrenheit is equivalent to a temperature increase of

5

9

degree celsius.

a temperature increase of 1 degree celsius is equivalent to a temperature increase of 1.8 degrees fahrenheit.

a temperature increase of

5

9

degree fahrenheit is equivalent to a temperature increase of 1 degree celsius.

a) i only

b) ii only

c) iii only

d) i and ii only

answer:

my guess it 8 i'm probably wrong
