In a turbofan engine, the bypass ratio (BPR) is defined as the ratio of:
(A) Mass flow rate through the bypass duct to mass flow rate through the engine core
(B) Core mass flow rate to total inlet mass flow rate
(C) Turbine inlet temperature to compressor inlet temperature
(D) Fan pressure ratio to compressor pressure ratio
Answer Key:
A
Step-by-Step Verified Solution
### Solution: Bypass ratio BPR = \dot{m}_{bypass} / \dot{m}_{core}. Correct: A.
