Question

Ideal gas with constant specific heat (static specific heat ??0 , Specific heat ratio ?) per unit mass in the polytropic process (index: ?) The amount of micro heat transfer received by the sieve can be calculated by ?? = ?? ∙ ??. Cn is called the polytropic constant.

(a) Deduce the polytropic specific heat in terms of exponent ?, specific heat and static specific heat ??0. (? ≠ 1)

(Hint: Polytropic course can also be written as ?? ^ (?−1) = const.)

(b) Using the equation for micro heat transfer, show that the process with 1 <? <? starting at the initial condition(T1, s1) is expressed as a negative exponential function on the T-? line.
