In an ideal otto cycle, air is compressed from 25 c and 2 l to 0.16 l, and its temperature increases by an additional 800 c during the heat addition process. determine the thermal efficiency of the cycle. account for the constant specific heats at room temperature. assume cp = 1.005 kj/kg. k and k=1.4.

η = 0.635  or 63.5 %

Explanation:

Given that

T₁=25 C

V₁= 2 L

V₂=0.16 L

We know that compression ratio(r) in Otto cycle given as

 r= V₁ /V₂

r= 2 / 0.16

r=12.5

We know that efficiency to cycle given as

tex]\eta =1-\dfrac{1}{r^{k-1}}[/tex]

By putting the values

η = 0.635  or 63.5 %

answer:

d. attempt to find the owner, then leave your information if you cannot find them.

explanation:

d. represents both (b) and (c).

more logical as well.

b and c are to complicated.

glad i could , give me a follow, so if you need with any other question, im here.
