Calculese el voltaje inducido en una bobina estacionaria de 500 vueltas que se produce en los siguientes cambios de flujo; (a) el incremento de 4wb a 6wb en 1 s;(b) la disminucion de 6 wb a 4wb en 1 s; (c) 4000 lineas de flujo que aumentan a 5000 lineas en 5 μs; (d) a 4 wb permaneciendo constante durante 1 s.

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.

Determine whether or not it is possible to compress air adiabatically from k to 140 kpa and 400 k. what is the entropy change during this process?

The higher the astm grain-size number, the coarser the grain is. a)-true b)-false
