Question

Common Data Question:

In two air standard cycles - one operating in the Otto and the other on the Brayton cycle - air is isentropically compressed from $300$ to $450,K$. Heat is added to raise the temperature to $600K$ in the Otto cycle and to $550K$ in the Brayton cycle.

If $W_o$ and $W_B$ are work outputs per unit mass, then

• A. $W_o>W_B$
• B. $W_o<W_B$
• C. $W_o=W_B$
• D. It i not possible to calcuatle the work outputs unless the tmeperture after the expansion is given

Answer 1

The correct option is A $W_o>W_B$

$W_o>W_B$
