This spreadsheet calculates thermodynamic and transport properties of a few gaseous, liquid and solid species (TP), according to International units. The user can analyze power cycles (Carnot, Brayton, Otto, Diesel and MHD), power cycle components and processes (compression, combustion and expansion) and compressible flow (velocity of sound, Mach number, stagnation and static properties, nozzle, normal shock, diffuser and thrust)
