It looks like you've uploaded a thermodynamics exam problem involving a gas turbine cycle. The first problem provides thermodynamic coefficients for the fluid and asks you to determine the equation of state and its variation with pressure. The second problem describes a turbine cycle with transformations such as adiabatic compression and heat exchange, and asks for specific calculations.

Would you like to go through a specific part of the problem? If you could specify which part you'd like help with, I can guide you through the necessary steps!
