Bypass Exhaust Velocity given Turbofan Thrust Solution

Follow our step by step solution on how to calculate Bypass Exhaust Velocity given Turbofan Thrust?

FIRST Step Consider the formula

V j,b = \frac{T - m c \cdot (V j,c - V)}{ṁ b} + V

Next Step Substitute values of Variables

∴

V j,b = \frac{17.8kN - 43kg/s \cdot (300m/s - 198m/s)}{258kg/s} + 198m/s

Next Step Convert Units

∴

V j,b = \frac{17800N - 43kg/s \cdot (300m/s - 198m/s)}{258kg/s} + 198m/s

Next Step Prepare to Evaluate

∴

V j,b = \frac{17800 - 43 \cdot (300 - 198)}{258} + 198

Next Step Evaluate

∴

V j,b = 249.992248062016m/s

LAST Step Rounding Answer

∴

V j,b = 249.9922m/s
