Abstract: A computer pa-agram GASCOMP2 has been developed to analyze the characteristics of a natural gas reciprocating or centrifugal compressor for compressor selection and structural design. The natural gas compressibilityz is calculated according to two equations of state, BWR and RIB. Gonversions between English system, metric system, and SI units are given. This program allows for variation of natural gas composition, is adaptable to any combination of input-output units, and has high accuracy. It has been used on PC-1500A computes and can be used on other microcomputers with slight modification of syhtax.

摘要： 程序GASCOMPZ用于天然气往复式或离心式压缩机的特性分析,以便压缩机选型、结构设计。程序提供了天然气压缩因数z基于BWR和RK状态方程的两种算法,提供了英制、米制和国际单位制之间的换算程序。因而对计算课题天然气组分的变化、输入-输出单位制的组合通应性强,计算精度较高。该程序曾应用在YC-1500A计算机上,若对个别句法稍作修改,也可毗在其他型号的微机上。
