1. The total pressure for the CO2​:N2​:He(1:1:8) mixture is (5Torr) which corresponds to an N Value of approximately 1017 cm−3. The E/N value is 3×10−16 V⋅cm2 and ne=1010 cm−3. Calculate the total CO2​−N2​ electrical power density and . the electron temperature

 In thermal electric generating plant, overall efficiency is improved when

a.  Boiler pressure is increased

b.  The difference between initial pressure and temperature and exhaust pressure and temperature are held at a maximum

c.  Load on the units is increased

d.  Increased the no. of generator
