Liquid nitrogen is stored in 0.5-m3 metal tanks that are thoroughly insulated. Consider the process of filling an evacuated tank, initially at 295 K. It is attached to a line containing liquid nitrogen at its normal boiling point of 77.3 K and at a pressure of several bars. At this condition, its enthalpy is -120.8 kJ kg-1. When a valve in the line is opened, the nitrogen flowing into the tank at first evaporates in the process of cooling the tank. If the tank has a mass of 30 kg and the metal has a specific heat capacity of0.43 kJ kg-1 K-1, what mass of nitrogen must flow into the tank just to cool it to a temperature such that liquid nitrogen begins to accumulate in the tank? Assume that the nitrogen and the tank are always at the same temperature. The properties of saturated nitrogen vapor at several temperatures are given as follows:
L-Serine is an amino acid important for its roles in synthesizing other amino acids and for its use in intravenous feeding solutions. It is often synthesized commercially by fermentation, and recovered by subjecting the fermentation broth to several processing steps and then crystallizing the serine from an aqueous solution. The solubilities of L-serine (L-Ser) in water have been measured at several temperatures, producing the following data:5T(K) 283.4 285.9 289.3 299.1 316.0 317.8 322.9 327.1x(mole fraction L-Ser) 0.0400 0.0426 0.0523 0.0702 0.1091 0.1144 0.1181 0.1248One of the ways such data can be represented is with the van’t Hoff equation: ln x =( a=T b).Graph the data so that the resulting plot is linear. Estimate a and b and give their units.

Nitrogen is to be liquefied in a simple Linde process. The feed and recycle are mixed. compressed to 64 bar, and precooled to 135K. The vapor then passes through a heat exchanger for additional cooling before beinng throttled to 1 bar. The unliquefied fraction leaves the seperator at the saturation temperature and passes through the heat exchanger, then exits at 120 K. a. What fraction of the gas is liquefied in the process? b. What is the temperature of the high pressure gas entering the throttle valve?

A certain ideal heat engine uses water at the triple point as the hot source and an organicliquid as the cold sink. It withdraws 2.71 kJ of energy as heat from the hot source andgenerates 0.71 kJ of work. What is the temperature of the organic liquid?
A mixture of 87.3 mole % methanol and 12.7 mole % isopropyl alcohol is vaporized at 101.325 kPa (absolute) until 900 moles of vapor and 100 moles of liquid in equilibrium with each other are produced. This occurs in a single-stage system and the vapor and liquid are kept in contact until equilibrium is achieved. Calculate the composition of the vapor and liquid. Note: Assume the system exhibits ideal behavior (which it mostly does), e.g. Raoult’s Law applies and an Antoine’s Vapor Pressure correlation is a sufficiently accurate model of component vapor pressure.
