3. A steam turbine operates adiabatically and produces 4000 kW. Steam is fed to the turbine at 21 bar and 480°C. The exhaust from turbine is saturated steam at 0.1 bar and it enters the condenser where it is condensed and cooled to 30°C. What is the steam rate for the turbine, and at what rate must cooling water be supplied to the condenser if the water enters at 15°C and is heated to 25°C.

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
