Here is how the Brayton Cycle Efficiency equation looks like.

0.668 = 1 - \frac{1}{6^{\frac{2.6 - 1}{2.6}}}

0.668 = 1 - \frac{1}{6^{\frac{2.6 - 1}{2.6}}}

0.668 = 1 - \frac{1}{6^{\frac{2.6 - 1}{2.6}}}

Brayton Cycle Efficiency Solution

Follow our step by step solution on how to calculate Brayton Cycle Efficiency?

FIRST Step Consider the formula

BCE = 1 - \frac{1}{{r p}^{\frac{Y - 1}{Y}}}

Next Step Substitute values of Variables

∴

BCE = 1 - \frac{1}{6^{\frac{2.6 - 1}{2.6}}}

Next Step Prepare to Evaluate

∴

BCE = 1 - \frac{1}{6^{\frac{2.6 - 1}{2.6}}}

Next Step Evaluate

∴

BCE = 0.668000299386509

LAST Step Rounding Answer

∴

BCE = 0.668
