A 0.8 m long cylindrical burning chamber is 0.2 m in diameter. The hot gases within it are at a temperature of 1500?C and a pressure of 1 atm, and the absorbing components consist of 12% by volume of CO2 and 18% H2O.
Neglect end effects and determine how much cooling must be provided the walls to hold them at 750?C if they are black.
