The volume fraction of particles in a wc-particle cu-matrix cermet is 0.65 calculate the minimum expected elastic modulus, in gpa, of this particle reinforced composite. the moduli of the two components are 682 gpa and 110 gpa, respectively. use what you know about these composite phases to discern which modulus is which. answer format: x unit: gpa 127.

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.

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

Fluids at rest possess no flow energy. a)- true b)- false
