Mass Flow Rate Core - (Measured in Kilogram per Second) - Mass Flow Rate Core refers to the rate at which air flows through the core of a turbofan engine, specifically through the combustion chamber and the turbine.
Exit Velocity Core Nozzle - (Measured in Meter per Second) - Exit Velocity Core Nozzle is the speed at which exhaust gases exit the primary nozzle of a turbofan engine.
Flight Speed - (Measured in Meter per Second) - Flight Speed refers to the velocity at which an aircraft travels through the air.
Mass Flow Rate Bypass - (Measured in Kilogram per Second) - Mass Flow Rate Bypass refers to the rate at which air bypasses the core of a turbofan engine and flows through the bypass duct.

STEP 1: Convert Input(s) to Base Unit

Turbofan Thrust: 17.8 Kilonewton --> 17800 Newton (Check conversion here)
Mass Flow Rate Core: 43 Kilogram per Second --> 43 Kilogram per Second No Conversion Required
Exit Velocity Core Nozzle: 300 Meter per Second --> 300 Meter per Second No Conversion Required
Flight Speed: 198 Meter per Second --> 198 Meter per Second No Conversion Required
Mass Flow Rate Bypass: 258 Kilogram per Second --> 258 Kilogram per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_j,b = (T-m_c*(V_j,c-V))/ṁ_b+V --> (17800-43*(300-198))/258+198

Evaluating ... ...

V_j,b = 249.992248062016

STEP 3: Convert Result to Output's Unit

249.992248062016 Meter per Second --> No Conversion Required

FINAL ANSWER

249.992248062016 ≈ 249.9922 Meter per Second <-- Exit Velocity Bypass Nozzle

What is expansion velocity?

Velocity is the directional speed of an object in motion as an indication of its rate of change in position as observed from a particular frame of reference and as measured by a particular standard of time. It shows the expansion of the Universe by showing how distant galaxies are moving away from us.
