Hydrogen data for energy systems published

Scientists and engineers engaged in the research and design of energy systems will find help in a new National Bureau of Standards reference publication dealing with the physical properties of hydrogen. The publication encompasses comprehensive coverage of hydrogen over a wide range of pressures and temperatures. Ortho-para modification of the hydrocgen molecule is taken into consideration in presenting the properties of data. Hydrogen, methane, and gasoline combustion characteristicsare included. Engineering process design data are also included. 62 figures, 30 tables. (DP)
