With a given geometry and at a constant speed for the flow machinery, the mass flow and output increase in proportion to the pressure level of the cycle. All other pressures in the cycle increase at the same rate, which means the pressure ratios remains constant. Thus, for an ideal or semi-ideal gas at least, the temperatures and with this also the enthalpies remain constant as the pressure grows.

The following section describes the particular thermodynamic effects of charging on a gas turbine cycle.

4.1 Effect of the Pressure Level on Size
4.2 Effect of the Pressure Level on Efficiency
4.3 Effect of the Pressure Level on the Heat Exchanger
