Explanation: The term bypass ratio is used in turbofan.In turbofan some of the air enters the engine bypass and rotates the fan while the remaining air rotates the turbine where these two fan and turbine provides the drag force required.Bypass ratio is the ratio of air bypassing the engine to the ratio of air passing through the engine.
