Afossil-fired power plant uses an ideal saturated rankine cycle with a steam flow rate of 6500 lbm/hr. the boiler pressure is 1500 psia; and the condenser pressure is 2 psia. the plant capacity factor is 80%. determine: (a) the feedwater pump specific work, (b) the net power output (in kw or mw) of the cycle, and (c) the plant thermodynamic efficiency.

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
