Steam is generated in steam generators/boilers and is widely used in process heating and power plants.Students doing their diploma or from undergraduate, graduate or postgraduate fields would immensely benefit if they master the steam properties. Mechanical Engineering students, Professionals from any engineering background will find the content useful.Technicians, engineers or anybody working in industry must also have an introductory knowledge about steam.This course is therefore designed to provide an introductory knowledge of steam properties and especially the use of steam tables.Several terms like saturated liquid water, wet steam, dry saturated steam are explained in an easy to understand manner.The concept of saturation temperature or what is known as boiling point is clarified.Terms like specific enthalpy of saturated water, dry saturated steam and wet steam are explained and use of steam tables to extract these properties is explained with the help of examples. Terms like specific volume of saturated water, dry saturated steam and wet steam are explained and use of steam tables to extract these properties is explained with the help of examples. Terms like specific entropy of saturated water, dry saturated steam and wet steam are explained and use of steam tables to extract these properties is explained with the help of examples. The concept of dryness fraction is explained.The device used for measuring dryness fraction of steam is separating and throttling calorimeter.Basic working and principle of the calorimeter is explained Procedure to determine dryness fraction of steam is explained Calculations involving separation and throttling of wet steam to superheated steam in the calorimeter and ways of determining the dryness fraction using steam tables and using typical measurements is brought forthAnybody will understand the use of steam tables and steam properties after completing this course
