This appendix has been prepared to facilitate the calculation and correction of turbine test results by furnishing numerical examples of the procedures outlined in PTC 6, the Performance Test Code on Steam Turbines. The feedwater heating cycles and gland leak-off systems have been simplified by avoiding unnecessarily long or repetitive calculations while still demonstrating the basic principles involved. The general guidelines for making these calculations and comparisons to specified performance are given.<\/p>\n
