Weight flow, w, may be calculated from any conditions of interest using the following equation (derived from Equation 100-3): Refer to the nomograph in Appendix…

Flow through a compressor may be stated in a number of different ways: • MMSCFD • Moles/Hour (MPH) • SCFM • ACFM • Weight Flow…

For air compressors it is usually necessary to account for water vapor content. It is important to know the moisture content accurately when a process…

The specific gravity of the gas mixture is determined by dividing the molecular weight of the mixture by that of air.

Knowing the mole fractions in a mixture leads to calculation of several important properties of the mixture: • the molecular weight, Mm • molal specific…

Equation 100-1 defines the behavior of a “perfect” gas in terms of variables listed: pressure, temperature, volume, etc. This is a helpful starting point, although…

Positive displacement compressors perform work on the gas in a repetitive noncontinuous process. The types within this category include: • Reciprocating • Rotary – Screw…

Dynamic compressors develop a rise in pressure by increasing the kinetic energy of the gas flow on a continuous basis. The types within this category…
