The pressure and temperature at the beginning of compression of an air-standard diesel cycle are 95 kpa and 300 k, respectively. at the end of the heat addition, the pressure is 7.2 mpa and the temperature is 2150 k. determine (a) the compression ratio. (b) the cutoff ratio. (c) the thermal efficiency of the cycle. (d) the mean effective pressure, in kpa.

Afan that can provide air speeds up to 60 m/s is to be used in a low-speed wind tunnel with atmospheric air at 35 c. if one wishes to use the wind tunnel to study flat-plate boundary layer behavior up to reynolds numbes of re 10, what is the minimum plate length that should be used? at what distance from the leading edge would transition occur if the critical reynolds nurnber were rer, e = 5 × 105?
