STEP 1: Convert Input(s) to Base Unit

Turbofan Thrust: 17.8 Kilonewton --> 17800 Newton (Check conversion here)
Mass Flow Rate Bypass: 258 Kilogram per Second --> 258 Kilogram per Second No Conversion Required
Exit Velocity Bypass Nozzle: 250 Meter per Second --> 250 Meter per Second No Conversion Required
Flight Speed: 198 Meter per Second --> 198 Meter per Second No Conversion Required
Mass Flow Rate Core: 43 Kilogram per Second --> 43 Kilogram per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

V_j,c = (T-ṁ_b*(V_j,b-V))/m_c+V --> (17800-258*(250-198))/43+198

Evaluating ... ...

V_j,c = 299.953488372093

STEP 3: Convert Result to Output's Unit

299.953488372093 Meter per Second --> No Conversion Required

FINAL ANSWER

299.953488372093 ≈ 299.9535 Meter per Second <-- Exit Velocity Core 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. Formula: v = Ho d where: v = velocity of a galaxy, in km/s.
