Primary Mass flow Rate in Turbofan Engine Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mass Flow Rate Core = (Turbofan Thrust-Mass Flow Rate Bypass*(Exit Velocity Bypass Nozzle-Flight Speed))/(Exit Velocity Core Nozzle-Flight Speed)
m_c = (T-ṁ_b*(V_j,b-V))/(V_j,c-V)
This formula uses 6 Variables

Variables Used

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.
Turbofan Thrust - (Measured in Newton) - Turbofan Thrust is the total thrust produced by jet core efflux and bypass air which has been accelerated by a ducted fan.
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.
Exit Velocity Bypass Nozzle - (Measured in Meter per Second) - Exit Velocity Bypass Nozzle is the speed at which exhaust gases exit the secondary nozzle of a turbofan exit.
Flight Speed - (Measured in Meter per Second) - Flight Speed refers to the velocity at which an aircraft travels through the air.
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.

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
Exit Velocity Core Nozzle: 300 Meter per Second --> 300 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

m_c = (T-ṁ_b*(V_j,b-V))/(V_j,c-V) --> (17800-258*(250-198))/(300-198)

Evaluating ... ...

m_c = 42.9803921568627

STEP 3: Convert Result to Output's Unit

42.9803921568627 Kilogram per Second --> No Conversion Required

FINAL ANSWER

42.9803921568627 ≈ 42.98039 Kilogram per Second <-- Mass Flow Rate Core
