Teaching Thermodynamics to Engineering Students: New Approach for Interpolation of Steam tables

This article is for teaching steam table interpolation to the first year engineering students. We present a systematic approach for interpolating steam tables. In the thermodynamics book, a double interpolation approach is mentioned to find state properties at a temperature and pressure which are not mentioned in the table. See the following thermodynamics books [Engineering Thermodynamics by J.B. Jones and R.E. Dugan; Thermodynamics by W.Z. Black and J.G. Hartley, and Applied Thermodynamics for Engineering Technologists by T.D. Eastop and A. McConkey]. In this work, we present bilinear interpolation approach for teaching such concepts. We found our approach easy to teach to engineering students.
