Two identical cylinders with a movable piston contain 0.4 mol of helium gas at a temperature of 300 k. the temperature of the gas in the first cylinder is increased to 506 k at constant volume by doing work w1 and transferring energy q1 by heat. the temperature of the gas in the second cylinder is increased to 506 k at constant pressure by doing work w2 while transferring energy q2 by heat.

find δeint, 1, q1, and wi for the process at constant volume.

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
