1、33.1CHAPTER 33PHYSICAL PROPERTIES OF MATERIALSALUES in the following tables are in consistent units toVassist the engineer looking for approximate values. For dataon refrigerants, see Chapter 29; for secondary coolants, seeChapter 31. Chapter 26 gives more information on the values formaterials used

2、 in building construction and insulation. Manyproperties vary with temperature, material density, and composi-tion. The references document the source of the values and pro-vide more detail or values for materials not listed here. Thepreparation of this chapter is assigned to TC 1.3, Heat Transferan
