Computational Calculation of Gas and Water Properties: Part 1

Calculation of gas and water properties are of great significance in petroleum and as well as transmission and processing industry dealing with these fluids. Because of their significance they have to be calculated quite frequently depending on composition and the existing conditions of pressure and temperature. Standard charts are available for reading the values in most cases, but that requires tremendous efforts to find the required chart and then have to interpolate, if the curve at the required conditions is not drawn. To overcome this problem, programming has been done in Visual Basic to calculate the desired property accurately and with great ease, showing the significance of in-house softwares, which at the same time are very economical. The work is divided into two parts; the first part deals with the gas properties while the second part deals with the computational calculation of water properties. The authors also give a good insight to the nonprogrammers about programming and how it can be accomplished specifically in their field.
