1/25/2024 0 Comments Thermodynamics calculator water![]() If you need grams per cubic meter, multiply moles by 18.02. This value of "n" corresponds to 100% relative humidity, so multiply by actual relative humidity to get the true value of moles per cubic meter. Then, use the ideal gas equation to calculate the number of moles per cubic meter. Multiply the calculated pressure by 100,000 to convert to Pa. Examine phase boundaries between the different phases of water. Where P is the vapor pressure of water, in bar Calculate thermodynamic properties of steam based on pressure and temperature. Assuming that water follows the ideal gas law, the number of moles per cubic meter can be calculated, as shown below. The average velocity: w q 4 D i 2 2.1 m / s and the Reynolds number: R e w D H 2.1 m / s 0.05 m 0. ![]() Step 2 is to calculate the Reynolds Number. In this example the calculator for water is used. Multiplying this partial pressure by the relative humidity will provide the actual partial pressure of water vapor at the given relative humidity. Step 1 Determine thermodynamic properties for the fluid in the pipe. Calculate online thermodynamic and transport properties of water and steam, based on industrial (IAPWS-IF97) or scientific (IAPWS-95) formulation. You may also find the following Physics calculators useful.The Antoine equation will allow you to calculate the vapor pressure of water at a given temperature, which will allow you to calculate the partial pressure of water at 100% relative humidity.
