## What is Thermo Physical Prop?

This app provides important thermo-physical property data on seventeen fluids that are very common in industrial applications. Data helps in computation of various parameters pertaining to flow system design involving heat and energy transfers.   This App can become very handy for engineers and students dealing with thermodynamics, fluid mechanics and heat transfers as a quick reference guide. 

Fluids:
Air, Steam, Water, Nitrogen, Oxygen, Hydrogen, Helium, CO2, Methane, Ethane, Chlorine, Ammonia, Argon, Hydraulic oil, HFC (R410A), Mercury, Sulfuric Acid.

Properties:
The property data is presented in SI and USCS units for the given pressure and temperature conditions.  Property data is displayed in two parts.  The first part is on transport properties that are common to all fluids and presented in home screen as shown in the screen shot.  The second part is displayed as plus properties that are exclusively for gases and steam as given below.
  
•Thermo-physical Transport properties.
   o Density (ρ) – function of temperature and pressure
   o Viscosity (μ) – function of temperature
   o Specific Heat (cp) – function of temperature
   o Thermal conductivity (K) – function of temperature

•Gas properties
  o Molecular wt. (MW)
  o Specific heat ratios (cp/cv)
  o Thermal diffusivity (α)
  o Prandtl number (Pr)

For steam, additional thermodynamic property data are provided in the form of a Steam Table covering all 3 states such as saturated water, saturated vapor and superheat conditions at a given pressure and temperature.   Besides, a separate section is provided for saturation properties where users can choose either temperature or pressure as primary argument as shown in the screen shot.

Similarly for Air, there is a section on humid air properties that are consistent with psychrometric chart.  Users can choose either wet-bulb temperature or relative humidity as primary argument in addition to dry bulb temperature.  The result includes humidity ratio, dew point temperature, specific volume, specific enthalpy and entropy for both dry and humid air as shown in the screen shot.  In addition app notes has a link to a complete documentation on implementation and validation of math-models with industry examples.

Refrigerant Freon-R12 is no longer used in any HVAC or industrial applications.  Therefore it has been replaced with HFC R410A and app provides transport properties and vapor pressure data for a given saturated liquid temperature. 

It is often very cumbersome to read and interpolate these data from a chart or a reference table.  Therefore, this app can be very useful for all HVAC personnel including students for obtaining these data with speed and accuracy at given operating temperature and pressure.

## Key features

### 1/5 — If I could get a refund I would

*2024-10-24, version 2.4*

The scroll bar doesn’t show up. So it’s a mystery how to select your substance. 
I was expecting propane, butane, etc. but they weren’t included.

### 1/5 — Do not upgrade unless you have iOS 6!

*2013-09-12*

Beware: this new version does not work on devices with iOS 5. It's developers failed to declare that.

### 3/5 — Good starting point

*2012-05-05, version 1.2*

For the price it charges, it should be better. On obvious place that can be improved is the steam table. E. g., one ca easily add a function that calculates saturated steam pressure for given temperature; and vise versa.
