Excerpt from Molar Heat Capacity (CV) For Saturated and Compressed Liquid and Vapor Nitrogen From 65 to 300 K at Pressures to 35 MpaThe spherical bomb depicted in Fig. 1 is con structed of Type 316 stainless steel with a wall thickness of cm and an internal volume of cm3 at 100 K. To prepare for an isochoric experiment, N2 was charged at a pressure of 10 mpa and at a suitable bomb temperature until the target density was obtained. Then the sample was cooled to near 63 K with liquid Ne refrigerant, or to near 80 K when liquid N2 was used. Each run commenced in the vapor+liquid region. The heater power was set to obtain about a 4 K temper ature rise during each experiment. Apparatus con trol was then turned over to the microcomputer. A Fortran program was responsible for control of the cell heater. The guard and shield heaters followed the rise of the cell temperature using a specially tuned proportional-integral-derivative algorithm The program recorded, at periodic intervals, the bomb temperature, the cell pressure, and the voltage and current applied to the cell heater. Another Fortran program calculated heat capacity using the raw data as input. The raw data were not processed when the initial (t1) and final (t2)About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
