Question

A 15 kg/sec of a gas mixture at 100°C contains 0.7% N2 and the remaining is O2.
Calculate the amount of energy that can be carried by this mixture if the enthalpy of these two gases are 387 and 69 kJ/kg.

Answer 1

Answer:

The amount of air in excess of the stoichiometric amount is called excess air. The amount of excess air is usually expressed in terms of the stoichiometric air as percent excess air or percent theoretical air. For example 150% = 1.5 × the theoretical air.
