Engineering

1. For the two processes given below, determine the final temperature, pressure, specific volume, and the changes in internal energy, enthalpy, and entropy.

a. Air at 4500 K and 450 kPa go isothermally to 8 kPa.

b. Hydrogen at 2033 K and 132 kPa go isentropic ally to 497 K.

2. Calculate the final temperature and change in specific internal energy as steel at 212 kPa and 533 K goes insenthalpically to640 kPa.

3. Determine the changes in internal energy, enthalpy, and entropy as engine oil at 70 kPa and 298 K goes to 100 kPa and 420 K.

4. What are the enthalpy, internal energy, specific volume, and entropy for steam at 1107?C and 27 MPa?
