Suppose that a class CalendarDate has been defined for storing a calendar date with month, day and year components. (In our section handout, the class was called Date, but we have renamed it here because Practice-It uses a class named Date for other purposes.) The class includes the following members:

Air is compressed isentropically from an initial state of 300 k and 101 kpa to a final temperature of 1000 k. determine the final pressure using the following approaches: (a) approximate analysis (using properties at the average temperature) (b) exact analysis

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?

State the stress optic law in two dimension and obtain an expression for the same.
