INTRODUCTION The data in this book as been utilized to predict the wall temperature in fuel injectors of Microturbines. The study required the determination of the wall temperature in contact with the fuel. Coking was avoided by the proper design of the injectors such as thermal insulation. The purpose of this book is to provide engineers and designers in the aerospace and allied industries with a ready source of pertinent data on fuels, lubricants, and hydraulic fluids. An effort has been made to show representative property values, rather than values descriptive of individual commercial products. Wherever possible, in fact, the average of a number of typical values has been provided to cover the properties of a particular class of products. It must be recognized, therefore, that values for an individual product might depart somewhat from these characteristic values
