Calculators Overview

Thermodynamic calculators for air/gas systems using vacuum pumps, fans, blowers, compressors and heat exchangers.  Data in English & SI.

Gas Flow Calculator
Converts actual volume, standard volume and mass flows.

Equilibrium Temperature Calculator
Determine the equilibrium temperature for pneumatic conveying air and conveyed product.

Psychrometric (temperature/humidity) Calculator
Given an ambient condition and flow, calculate air and water vapor (humidity) mass flow, dew point and relative humidity before and after vacuum pumps, blowers, compressors and heat exchangers.  Also reports heat loss or gain.
