An insulated system is divided into 2 parts by a partition . one part of the tank contain 2.5 kg of compressed liquid water at 60 C and 600 kPa while the other part is evacuated. the partition is now removed, and the water expands to fill the entire tank. Determine the final temperature of the water and the volume of the tank for a final pressure of 10 kPa.
The Brayton cycle shown in figure 6.41 operates using CO2 as a working fluid with compressor and turbine isentropic efficiencies of 1.0. Calculate the thermal efficiency of this cycle when the working fluid is modeled.
Calculate real gas pseudopressure at a pressure of 1902.7 psia using the following data and a base pressure of 102.7 psia. Was the calculation of real gas pseudopressure necessary for this gas? Explain your answer.
