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?
Explanation: Given: Pi = 0.821 atm, Vi = 793 cm3 , and Vf = 86 cm3 . Using the relation We find that = 18.4089 atm.
Explanation: Given: Pi = 0.821 atm, Vi = 793 cm3 , and Vf = 86 cm3 . Using the relation
