Problem

One mole of a diatomic ideal gas (

\gamma = 1.4

) is taken through a cyclic process starting from point A. The process

A \to B

is an adiabatic compression,

B \to C

is isobaric expansion,

C \to D

is an adiabatic expansion, and

D \to A

is isochoric. The volume ratios are

V_A/V_B = 16

and

V_C/V_B = 2

and the temperature at A is

T_A = 300 \text{ K}

. Calculate the temperature of the gas at the points B and D and find the efficiency of the cycle.
