Determine the impact of the following parameters on transition on a flat plate (a) effect of roughness (b) effect of pressure gradient (c) effect of compressibility sketch the variation of transition re as a function of these parameters or use some other appropriate means to highlight the effect of these parameters. discuss the implications of these parameters on the overall drag note that, information regarding these effects is available in books and also in published journal papers and it is expected that you dig this out.

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
