Se quema n-octano [C8H18(l)] en la cámara de combus- tión de presión constante del motor de un avión con 70 por ciento de exceso de aire, que entra a la cámara de combustión a 600 kPa y 327 °C. Se inyecta combustible líquido a 25 °C, y los productos de combustión salen a 600 kPa y 1 227 °C. Determi- ne la generación de entropía y la destrucción de exergía por unidad de masa de combustible durante este proceso de com- bustión.

Two technicians are discussing the intake air temperature (iat) sensor. technician a says that the computer uses the iat sensor as a backup to the engine coolant temperature (ect) sensor. technician b says that the powertrain control module (pcm) will subtract the calculated amount of fuel if the air measures hot. who is correct

Acompressor receives the shaft work to decrease the pressure of the fluid. a)- true b)- false

Ahot wire operates at a temperature of 200°c while the air temperature is 20°c. the hot wire element is a tungsten wire of 5 um diameter and 2 mm in length. plot using excel current, heat transfer and heat generated by the wire for air velocity varying from 1-10 m/s in steps of lm/s? matlab the sensor voltage output, resistance, or assume nu 0.989 re033pr13 take air properties at tr (200°c20°c)/2 = 110°c properties of tungsten: c 0.13 kj/kg. k 3 p 19250 kg/m k (thermal conductivity) = 174 w/m. k
