Effective speed ratio Solution

STEP 0: Pre-Calculation Summary

Formula Used

Effective Speed Ratio = Flight Speed/Exit Velocity
α = V/V_e
This formula uses 3 Variables

Variables Used

Effective Speed Ratio - Effective Speed Ratio is the ratio of aircraft forward speed to the aircraft jet velocity.
Flight Speed - (Measured in Meter per Second) - Flight Speed refers to the velocity at which an aircraft moves through the air.
Exit Velocity - (Measured in Meter per Second) - Exit Velocity refers to the speed at which gases expand at the exit of nozzle of a engine.

STEP 1: Convert Input(s) to Base Unit

Flight Speed: 111 Meter per Second --> 111 Meter per Second No Conversion Required
Exit Velocity: 248 Meter per Second --> 248 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

α = V/V_e --> 111/248

Evaluating ... ...

α = 0.44758064516129

STEP 3: Convert Result to Output's Unit

0.44758064516129 --> No Conversion Required

FINAL ANSWER

0.44758064516129 ≈ 0.447581 <-- Effective Speed Ratio
