Factors that influence gas turbine performance

A gas turbine is a dynamic internal combustion engine. When we compare the performance of a gas turbine to that of a steam turbine, it becomes immediately evident that steam turbine performance is much easier to calculate, since both the vapor and the vapor conditions are fixed. For a gas turbine, the vapor condition depends on the type of fuel used and the atmospheric conditions. This is
