Question

If the turbine nozzle operates at a higher pressure ratio than the design value, then it is called as

• A. super critical condition
• B. critical condition
• C. subcritical condition
• D. abnormal condition

Hint:

Supercritical flow means operating beyond critical pressure ratios.

Answer 1

The Correct Option is A

A nozzle operating at a pressure ratio above its design condition is in supercritical flow, where exit velocity can become supersonic.
