You have a system that contains a special processor for doing floating point operations. You have determined that 50% of your computations can use the floating point processor. The speed-up of the floating point processor is 10. What percentage of the computations should be able to use the floating point processor in order to achieve an overall speedup of 2

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
