Question

At the exhaust of a turboject engine the nozzle is operating steadily and heat loss is assumed negligible. If the specific enthalpy of fluid and velocity of fluid at the inlet are 3232 kJ/kg and 269 km/hr respectively. At the exit the specific enthalpy of fluid is 2526 J/kg. Calculate the exit area (in mm2)of the nozzle when the specific volume at the nozzle exit is 0.67 m3/kg at the inlet area of 0.20 m2 and the specific volume at the inlet is 0.34 m3/kg. You do not need to include the unit for this question. Calculate answer to 3 d.p.

Step 1

72 m/s Specific enthalpy at exit, h2 = 2526 J/kg Specific volume at exit, v2 = 0.67 m^3/kg Using the steady flow energy equation: h1 + (C1^2)/2 = h2 + (C2^2)/2 Substitute the given values: 3232000 + (74.72^2)/2 = 2526 + (C2^2)/2 Solve for C2: C2 = 1190.62 m/s Show more…
