STEP 1: Convert Input(s) to Base Unit

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
Exit Velocity Bypass Nozzle: 250 Meter per Second --> 250 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

T = m_c*(V_j,c-V)+ṁ_b*(V_j,b-V) --> 43*(300-198)+258*(250-198)

Evaluating ... ...
