Flight Speed - (Measured in Meter per Second) - Flight Speed refers to the velocity at which an aircraft travel through the air.

STEP 1: Convert Input(s) to Base Unit

Net Thrust of Turbojet: 469 Newton --> 469 Newton No Conversion Required
Nozzle Exit Area: 0.0589 Square Meter --> 0.0589 Square Meter No Conversion Required
Nozzle Exit Pressure: 982 Pascal --> 982 Pascal No Conversion Required
Ambient Pressure: 101 Pascal --> 101 Pascal No Conversion Required
Mass Flow Rate Turbojet: 5 Kilogram per Second --> 5 Kilogram per Second No Conversion Required
Fuel Air Ratio: 0.008 --> No Conversion Required
Flight Speed: 130 Meter per Second --> 130 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_e = (T-A_e*(p_e-p_∞))/(m_a*(1+f))+V --> (469-0.0589*(982-101))/(5*(1+0.008))+130

Evaluating ... ...

V_e = 212.759742063492

STEP 3: Convert Result to Output's Unit

212.759742063492 Meter per Second --> No Conversion Required

FINAL ANSWER

212.759742063492 ≈ 212.7597 Meter per Second <-- Exit Velocity
