Superheated steam from the boiler is delivered to a turbine at 650 C and 8.5 MPa. The turbine exhausts at 0.01 MPa. If the turbine is 75% efficient, determine: a. The actual work of the turbine. b. The actual outlet temperature and quality (if applicable) of the exhaust from the turbine. c. If the steam exhaust is condensed (in a condenser) to a saturated liquid, what is the work required by the pump to bring the liquid to the boiler pressure (8.5 MPa)

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

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

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
