A car of mass 1100 kg drives with a velocity such that it has a kinetic energy of 400 kJ. Find its speed. If the car is raised with a crane, how high should it be lifted in the standard gravitational field to have a potential energy that equals the kinetic energy?
For nitrogen, Tc=126.2 K, Pc=33.84 bar and the ideal gas heat capacity is CP* [J/mol-K] = 28.883 – 0.157 x 10-2 T + 0.808 x 10-5 T2 – 2.871 x 10-9 T3, where T=T[K]. Using only this data, calculate CV and CP for nitrogen at 200K and 100 bar. Assume that Redlich-Kwong equation applies and that the equation of state parameters can be calculated from these critical parameters.
Oxygen is placed in a well-insulated tank of volume 0.2 m3 at an initial temperature of 180K and a pressure of 110 bar. Using the van der Waals equation of state, calculate the final temperature and pressure after half of the original amount of oxygen is removed from the tank.
The problems tells me to assume that the heat capacity for oxygen in the ideal gas state is given by CP* [J/mol-K] = 25.46 + 1.52 x 10-2 T[K]. The parameters for oxygen for the van der Waals equation of state are: a=0.1381 [Pa m6/mol2] and b = 3.184 [(m3/mol) x 10 5]. (Hint: this is solved with an entropy balance).

Sand and Surf Retailers recently acquired several smaller companies to expand its chain of clothing outlets. To establish consistency for the current organization and future acquisitions, Sand and Surf decided to develop an in-house application called SPS (Standard Purchasing System). The SPS system would standardize purchasing practices for each Sand and Surf subsidiary and manage all purchasing information. System testing will be completed by the end of the week.
