Abstract: In varying specific heat mixing of parallel streams, approximate treatments with constant specific heat are generally used. Recent derivations of varying specific heat gasdynamic functions by the author give powerful tool of solving the problem. This paper puts forward an accurate solution with five k’S and also a subaccurate solution with three k’s, being rather near to accurate. Yet constant specific heat solution gives appreciable errors.
