An unknown gas undergoes an isentropic process and expands from 1200 kpa and 1.15 m /kg to 100 kpa pressure. if the isentropic exponent and the specific heat at constant pressure for this gas are known to be 1.667 and 5.19 kj/kg. k respectively, calculate (a) the final specific volume in [m/kg] and b) the final temperature in [oc] for the gas at the end of the process.

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
