Question: A 0.61 m radius hemisphere (811 K surface temperature) is filled with a gas mixture at 533 K and 2-atm pressure containing 6.67 percent CO2

A 0.61 m radius hemisphere (811 K surface temperature) is filled with a gas mixture at 533 K and 2-atm pressure containing 6.67 percent CO2 and water vapor at 0.5 percent relative humidity. Determine the emissivity and absorptivity of the gas, and the net rate of radiant heat flow to the gas.GIVENA hemisphere filled with a gas mixtureHemisphere radius (r) = 0.61 mHemisphere surface temperature (T1) = 811 KGas temperature (Tm) = 533 KGas pressure (pT) = 2 atmGas mixture: 6.67% of CO2 and water vapor at R.H. = 0.5%ASSUMPTIONSThe hemisphere surface is black (ε1 =1)

A: T = 811 K E = 1.0 Gas (M) Tm 533 K r= - 0.61 M
