ISBN: 9783662532195. Some scientific and engineering data online. Joseph Henry Keenan graduated from MIT in 1922 with the degree of Bachelor of Science in naval architecture and marine engineering. Steam is an invisible gas consisting of vaporized water, which is formed when water boils. Under superheated or subcooled conditions, properties such as enthalpy, entropy and specific volume are dependent on temperature and pressure. However, at saturated conditions where a mixture of steam and water coexist, an additional parameter, steam quality, needs to be defined.
