"This program, designed for the HP-41CV calculator, will provide:
1. Compressibility factor Z, dimensionless.
2. Specific weight (or density), lb/ft³.
3. Mixture molecular weight M, dimensionless.
4. Mixture critical temperature T⒞, °R.
5. Mixture critical pressure P⒞, psia.
6. Mixture ratio of specific heats C⒫/C⒱, dimensionless.
7. Mixture normal boiling point latent heat of vaporization HV, Btu/lb.
…
…Two programs are available. Program A calculates items 1–5 and program B calculates items 6–7. Initiate desired program by pressing A or B."
