摘要：
A program having several novel features has been developed to determine two-phase pressure drop in horizontal lines. The program uses the semiempirical method of Lockhart and Martinelli, and is written for the Texas Instruments TI-59 programmable calculator used with the PC-100C printer. The program: calculates single-phase pressure drop in pipe for either gas or liquid flow; calculates pressure drop in horizontal pipe for two-phase flow; permits unusually rapid pressure-drop calculations - between 10 and 20 s for execution; yields outputs adequate for permanent records; permits easy change of operating data; option-solves for ideal-gas density, using a self-prompting mode of operation; and can be used with a calculator without printer; pertinent calculated results are stored in data registers.
