This nomogram provides a way to make a quick estimate of the exhaust temperature of a gas turbine, given the values of turbine efficiency, expansion ratio, and inlet temperature. For adiabatic expansion of the gas in the turbine, the temperature drop may be calculated as follows: where: T/sub 1/ =initial absolute temperature; T/sub 2/ =final absolute temperature; r =expansion ratio; e =turbine efficiency; and k =ratio of specific heats, c /SUB p/ /c /SUB v/ The nomogram solves this equation. For convenience, the temperature scales are graduated in degrees Celsius rather than Kelvin.
