Material properties (c_{p} = c_{v} and v = 1/ρ) of solids and liquids upon which the SL (solid/liquid) model is built. In the state TESTcalc, simply select the working substance and click Calculate to display the material properties. 

Saturation and superheated tables for phasechange (PC) fluids. In the PC TESTcalc, select the working fluid (from more than 60 fluids), enter two independent thermodynamic properties (say, p and h: all thermodynamic properties are colored blue) to obtain all other properties. 
R134a 
R22 
R12 
Ammonia (NH_{3}) 
N2 
Propane (C_{3}H_{8}) 

Material properties  c_{p}, c_{v}, R, k, etc.  upon which the perfect gas (PG) model is built. In the PG state TESTcalc, select the working fluid and click Calculate to display the material properties. 

Polynomial relation and tabular data for c_{p} as a function of absolute temperature T. To obtain c_{p} from the IG TESTcalc, select the gas, enter a temperature, and click Calculate. You may also obtain the temperature by entering a value for c_{p}. 
Ideal gas (IG) tables for several gases. In the IG TESTcalc, you wil find a much wider selection of gases. Select a gas, enter two independent thermodynamic properties and click Calculate for a complete state. 


Critical properties of various fluids used in the real gas (RG) model. In the RG TESTcalc, select the fluid and click Calculate to display all the material properties including the critical properties. 
LeeKesler Charts 
Compressibility charts used in the real gas (RG) model. LeeKesler charts are based on ideal fluid assumption and NelsonObert charts are based on average data. In the RG TESTcalc, select a model by using the LK or NO radio button, select a fluid, enter two independent thermodynamic properties, and click Calculate to obtain the complete state. 
NelsonObert Charts 
BWR Coefficents 
Constants used in BenedictWebbRubin (BWR) equation of state. 

Traditional psychrometric chart for moist air. The MA (moist air) TESTcalc handles other moist gases beside air. After selecting the gas, enter the known thermodynamic (blue) properties to calculate the rest. 

Formation enthalpies, heating values, and equilibrium constants tables. Use the nIG mixture TESTcalc to obtain component and mixture properties, combustion TESTcalc to find heating values, and the chemical equilibrium TESTcalc to find equilibrium constant. 

Isentropic, normalshock, and barometric (variation of properties with altitude) table. In the gas dynamics TESTcalc, select a gas and click Calculate to populate the isentropic, normalshock, deltatheta (oblique shock), and PrandtlMeyer table (expansion fan) in the table panel. 

TableI (Conversion Table) 
Handy unit conversion table in a pdf file. An enhanced version of the unit conversion TESTcalc is available as a free Android app with an intuitive spinning wheel interface. Search for Engineering Unit Converter app in Google Play. 

TableJ (Equation Sheet) 
Frequently used equations for property evaluation and system analysis for manual solution in a compact pdf file. Launch the calculator TESTcalc (appears in a popup window) for quick engineering calculations.
