In heat transfer analysis, the heat flow through walls of a warm house on a cold day is considered as Lumped system heat transfer O Unsteady heat transfer O Steady heat transfer O One dimensional heat transfer According to Mayer's equation the relationship between two specific heat capacities and gas constant can be represented as, I. Cp=Cv+R; II. Cp-Ov=R: III. (y/y+1) R =Cv+R; IV. R/(y+1)=Cp-R O a. I, II, III, and IV O b. ll only O c. I only O d. l, ll and Ill only O e. I and II only Next pag
