T h e Physical and Thermodynamic Properties of Helium. Technical Report D-9027. By JESSE T SIMMOXS, Engineering and Research Division, TVm. R . LT'hittaker Co., Ltd. LVm. R. Whittaker Co., Ltd., 915 Korth Citrus Avenue, Los Angeles 38, California. 1957. 79 pp. 23.5 X 28.5 cm. Price, 810.00. The following properties of helium, expressed in engineering units, are listed over the pressure range 14.7 t o 6,000 pounds per square inch absolute and from -440" t o f600" F.: density, specific volume, compressibility factor, entropy, enthalpy, specific heats at constant pressure a n d a t constant volume, the ratio C,/ Cy, viscosity, thermal conductivity, sonic properties and diffusion. Graphs of these properties are given. There is also included a liniited amount of d a t a on air.I In general the properties of helium given in earlier treatises Lire converted into engineering units and smoothed t o even values of the arguments. One would have greater confidence in the tables if he did not read t h e introduction in which some strange thermodynamic statements appear. ( I ) Taken from
