ECONOMY OF EXPANSION. As regards the economy of expansion it will be found byreference to the Table No. 8 on the properties of saturatedsteam that the weight of a given volume of steam varies verynearly in proportion to its pressure that is, a cubic foot of steamat 60 pounds pressure weighs approximately twice as much asthe same volume at 30 pounds pressure. A given weight of steam represents the same weight ofwater that must be evaporated to produce it, consequently thelower the terminal pressure at the end of the stroke in a givencylinder the less will be the amount of water exhausted assteam; and as the measure of the work done in the cylinder bythe
