267. How many Curtis stages are contained in the turbine shown in the illustration
The illustration depicts one nozzle group feeding two rows of moving blades, which constitutes a single Curtis stage. A Curtis stage is defined as one nozzle followed by two or more rows of moving blades; multiple stages would require additional nozzle groups and distinct pressure drops, which are not present. Therefore, the correct answer is 1.
