Six nozzles and 2 orifices were calibrated in pairs, one of a pair with water 240 F, 2200 psia at the inlet and the other with steam 1050 F, 2000 psia at the outlet of an operating boiler. Pipe Reynolds numbers averaged 600,000 for the water and 4,000,000 for the steam. Coefficients were generally in agreement with ASME. Type 430 stainless steel proved a better material of construction for the steam conditions than 2-14 chrome-molybdenum steel. The latter material showed considerable rusting and pitting after less than 10 hours of operation.
