Answer:
Efficiency of an Otto cycle is = 47.47 %
Explanation:
Compression ratio (r) = 5
Ratio of specific heat ([tex]\gamma[/tex]) = 1.4
Efficiency of an Otto cycle is given by = 1 - [tex]\frac{1}{r^{\gamma - 1} }[/tex]
Put the values of r and [tex]\gamma[/tex] in above formula we get
Efficiency = 1 -[tex]\frac{1}{5^{1.4 - 1} }[/tex]
Efficiency = 0.4747 = 47.47 %
This is the efficiency of an Otto cycle.
