Wagner, W. January 1, Gas Turbines Power. January ; 1 : — This paper summarizes the need and the requirements for such a new industrial formulation and gives the entire numerical information about the individual equations of IAPWS-IF Moreover, the scientific basis for the development of the equations is summarized and the achieved quality of IAPWS-IF97 is presented regarding the three criterions accuracy, consistency along region boundaries, and computation speed. For comparison, corresponding results for the previous standard IFC are also presented.

This page provides supplementary data to the article properties of water. Further comprehensive authoritative data can be found at the NIST Webbook page on thermophysical properties of fluids. Except where noted otherwise, data relate to standard ambient temperature and pressure. Vapor pressure formula for steam in equilibrium with liquid water: . Data in the table above is given for water—steam equilibria at various temperatures over the entire temperature range at which liquid water can exist. Pressure of the equilibrium is given in the second column in k Pa.

Beginning in the International Association for the Properties of Water and Steam IAPWS recommended the use of a new model for calculation of the thermodynamic properties of water and steam. The latter model had been used for 30 years for the calculation of thermodynamic properties of water for industrial, scientific, and academic applications. The new model is oriented toward facilitating calculations employing computers, improving accuracy, and improving consistency among the model's limiting regions as well as contributing towards improved process design and simulation.

DOI: This paper describes the development of an optimization-friendly thermodynamic property model of water and steam that covers liquid, vapor, 2-phase as well as the super-critical region. All equations are at least twice continuously differentiable with respect to all model variables and can be used in dynamic optimization problems solved by efficient derivativebased algorithms.

Just as a map or GPS navigation system is necessary when driving in a new area or a flight timetable is indispensable when taking the plane, steam tables are essential to steam users in industry. This article will introduce steam tables, pointing out the different types and offering an overview of the different elements found within them. A saturated steam table is an indispensable tool for any engineer working with steam. It's typically used to determine saturated steam temperature from steam pressure, or the opposite: pressure from saturated steam temperature. In addition to pressure and temperature, these tables usually include other related values such as specific enthalpy h and specific volume v.
It seems that you're in Germany. We have a dedicated site for Germany. This book contains steam tables for practical industrial use calculated by using the international standard IAPWS-IF97 for the thermodynamic properties of water and steam and the IAPWS industrial standards for transport and other properties. The calculation of the properties is not only shown for the usual input parameter pairs pressure and temperature, but also for the parameters pressure and enthalpy, pressure and entropy, enthalpy and entropy. It is for the first time that such a description is given.

Updated 01 Aug Provided thermodynamic properties are:. Temperature Pressure Enthalpy Specific volume Density Specific entropy Specific internal energy Specific isobaric heat capacity Specific isochoric heat capacity Speed of sound Viscosity Vapour fraction. All properties can be calculated with the inputs, p and T known, p and h known, h and s known and some with pressure and density known. X Steam are a full implementation of the IF formulation including all regions and all backward functions for good calculation speed.
Но он не смог примириться с тем, что этот взрыв лишил его возможности познакомиться с собственной матерью. Произведя его на свет, она умерла из-за осложнений, вызванных радиационным поражением, от которого страдала многие годы.
Неожиданно для самой себя Сьюзан схватила беретту, и Хейл, открыв глаза, увидел ее, стоящую с револьвером в руке, нацеленным ему в низ живота. - Где ключ? - потребовала. Хейл с трудом пришел в. - Ч-что произошло. - То, что ты проиграл, а больше .
Это не доказательство, - сказал Стратмор. - Но кажется довольно подозрительным. Сьюзан кивнула. - То есть вы хотите сказать, Танкадо не волновало, что кто-то начнет разыскивать Северную Дакоту, потому что его имя и адрес защищены компанией ARA. - Верно.
