One mole of a diatomic ideal gas ( gamma = 1.4) is taken through a cyclic process starting from point 'A'. This process A to B is an adiabatic compression. B to C is isobaric CtoD 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^@ K. Calculate the temperature of the gas at the points 'B' and 'D' and find the efficiency of the cylcle.

1.	One mole of a diatomic ideal gas ( gamma = 1.4) is taken through a cyclic process starting from point 'A'. This process A to B is an adiabatic compression. B to C is isobaric CtoD 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^@ K. Calculate the temperature of the gas at the points 'B' and 'D' and find the efficiency of the cylcle.
