Abstract
The paper discusses methods of calculation of stage efficiency, cumulative heat, and reheat factor for a given steam turbine condition curve, together with the converse problem of the determination of the condition curve and reheat factor when the stage efficiency is given. The complications due to pressure loss, resuperheating and tapping for feed heating are considered. A set of graphs calculated by these methods is provided for reading off the relations between turbine efficiency, stage efficiency, and reheat factor with condition curves based on constant dry stage efficiency of small stages and standard wetness loss correction (1 per cent loss per 1 per cent wetness).
