Asimple non-ideal rankine cycle with water as the working fluid operates between the pressure limits of 15 mpa in the boiler and 125 kpa in the condenser. saturated steam enters the turbine. irreversibilities in the turbine cause the steam quality at the outlet of the turbine to be 70 percent. determine the isentropic efficiency of the turbine and the thermal efficiency of the cycle.

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
