Assume that nitrogen is available in a storage tank at 2 MPa and 210 K. On the following chart, show the path for the following scenarios. a) An expansion valve is connected to this tank that drops the fluid (i.e., nitrogen) pressure at its outlet to one atmosphere. b) A compressor is connected to this tank that raises the fluid pressure at its outlet to 10 MPa. c) A turbine is connected to this tank that drops the fluid pressure at its outlet to one atmospheric pressure. d) A heat exchanger is connected to this tank that raises the fluid temperature to 330K at its outlet. e) A heat exchanger is connected to this tank that drops the fluid temperature to 135K at its outlet. f) Show the process for the fluid to change its state from 2 MPa and 210 K to 14 MPa and 240 K. Identify the required equipment. g) If a coolant at 150 K is available, is it possible to change the state of nitrogen from 2 MPa and 210 K to saturated liquid at atmospheric pressure? If yes, identify the required equipment and illustrate the process on the chart.
