MCQ - 22-10489

Question:

Air in the cylinder of a diesel engine at 21.8° C is compressed from an initial pressure of 0.821 atm and of volume of 793 cm3 to a volume of 86 cm3. Assuming that air behaves as an ideal gas (γ = 1.40) and that the compression is adiabatic and reversible, then which of the following represents the final pressure of the air in the cylinder?

  1. 20.7545 atm
  2. 36.8402 atm
  3. 18.4089 atm
  4. 36.8402 atm

Correct Answer: D

Explanation:

Explanation:
Given: Pi = 0.821 atm,
Vi = 793 cm3 , and
Vf = 86 cm3 .
Using the relation

capture 1 -14956003
We find that
capture 2 -58038684
capture 3 -13193734
= 18.4089 atm.
