Bypass Mass Flow Rate Solution

STEP 0: Pre-Calculation Summary

Formula Used

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

Variables Used

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.
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.

STEP 1: Convert Input(s) to Base Unit

Mass Flow Rate: 301 Kilogram per Second --> 301 Kilogram 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

ṁ_b = m_a-m_c --> 301-43

Evaluating ... ...

ṁ_b = 258

STEP 3: Convert Result to Output's Unit

258 Kilogram per Second --> No Conversion Required

FINAL ANSWER

258 Kilogram per Second <-- Mass Flow Rate Bypass
