App for thermodynamic steam property calculation. Based on steam table IAPWS IF-97. THIS IS A PROFESSIONNAL APP, even it is free. Each calculation is made with high precision, even close to the critical point and high pressure, as major professionnal app. This app allow to calculate thermodynamic steam properties of steam and/or water, with following inputs: => Pressure + Temperature => Pressure + Enthalpy And, for calculation at saturation: => Quality + Pressure => Quality + Temperature => Quality + Volume => Temperature only => Pressure only Available on PRO version ONLY : => Pressure + Entropy => Pressure + Volume => Temperature + Volume => Temperature + Entropy => Enthalpy + Entropy => Calculation of transformation (heating/cooling, pressure reduction, etc...) => Graph T=f(H) Please send me any crash / suggestion / improvement
