Air enters a diffuser with an averaged velocity of 360 m/s at a stagnation pressure and temperature of 340 kpa and 420 k and leaves at a stagnation pressure of 300 kpa with an averaged velocity of 120 m/s and a static pressure of 285 kpa. determine, (i) the static pressure and mach number of the air at inlet; (ii) the diffuser efficiency; (iii)the mach number at exit and the overall entropy increase.

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
