Total mass flow rate through turbofan engine Solution

STEP 0: Pre-Calculation Summary

Formula Used

Mass Flow Rate = Mass Flow Rate Core+Mass Flow Rate Bypass
m_a = m_c+ṁ_b
This formula uses 3 Variables

Variables Used

Mass Flow Rate - (Measured in Kilogram per Second) - Mass Flow Rate represents the amount of mass passing through a system per unit of time.
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.
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

Mass Flow Rate Core: 43 Kilogram per Second --> 43 Kilogram 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

m_a = m_c+ṁ_b --> 43+258

Evaluating ... ...

m_a = 301

STEP 3: Convert Result to Output's Unit

301 Kilogram per Second --> No Conversion Required

FINAL ANSWER

301 Kilogram per Second <-- Mass Flow Rate
