Gas Turbine (cont.)GTURB-STACK-FUGTURB-TEX-FPLRGTURB-TEX-FTSteam TurbineSTURB-I/O-FPLRaccepts the U-narne of a CURVE-FIT instruction that definesthe coefficients a and b of the equation z = ax b . Theuser must use TYPE = QUADRATIC in the CURVE-FIT instructionand enter the coefficients as (a, b, 0). That equationwill be used to express the UA of a gas turbine exhaustheat exchanger as a function of electric output (see-STACK-FU).accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation will be usedto express the temperature of gas turbine exhaust gas as afunction of its part-load ratio.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation will be usedto express the gas turbine exhaust gas temperature as afunction of ambient air temperature.accepts the U-name of a CURVE-FIT instruction that definesa linear or quadratic equation. That equation will be usedto express the energy input/output ratio of a steam turbinegenerator as a function of its part-load ratio.V.47 (Revised 5/81)
