The temperature at the beginning of the compression process of an air-standard otto cycle with a compression ratio of 8 is 540°r, the pressure is 1 atm, and the cylinder volume is 0.02 ft'. the maximum temperature during the cycle is 3600°r. determine (a) the temperature and pressure at the end of each process of the cycle. (b) the thermal efficiency, and (e) the mean effective pressure, in atm.

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
