This application can be used to calculate properties of common fluids used in industry by temperature input. Fluid included are saturated water, saturated refrigerant 134a, saturated ammonia, saturated propane, liquid methane, liquid methanol, liquid isobutane, liquid engine oil, liquid mercury, liquid bismuth, liquid lead, liquid sodium, liquid potassium, air, carbon dioxide, carbon monoxide, methane, hydrogen, nitrogen, oxygen and water wapor. User can enter temperature in celcius, kelvin, fahrenheit, rankine, delisle, newton, reaumur and romer. After calculation properties such as chemical formula, melting point, boiling point, saturation pressure, liquid density, vapor density, enthalpy of vaporization, liquid specific heat, vapor specific heat, thermal conductivity, dynamic viscosity, prandlt number and volume expension coefficient are displayed. App also have multi language support and language can be changed from settings menu.
