1. What are the temperature, specific entropy, specific enthalpy and specific volume of superheated steam when: a. Pressure is 6 MPa and specific internal energy is 2792 kJ/kg
b. Pressure is 6 MPa and specific internal energy is 2902 kJ/kg
c. Pressure is 6.5 MPa and specific internal energy is 2892 kJ/kg

Two flowing streams of argon gas are adiabatically mixed to form a single flow/stream. one stream is 1.5 kg/s at 400 kpa and 200 c while the second stream is 2kg/s at 500 kpa and 100 ? . it is stated that the exit state of the mixed single flow of argon gas is 150 c and 300 kpa. assuming there is no work output or input during the mixing process, does this process violate either the first or the second law or both? explain and state all your assumptions.

What precautions should you take to prevent injuries when dealing with heavy loads?

The temperature of air decreases as it is compressed by an adiabatic compressor. a)- true b)- false
