A normal shock wave exists in Mach 2 stream of air having temperature and pressure of 45°F and 30 psia, respectively. Calculate the Mach number, pressure, and temperature downstream of the shock wave.

The thermal expansion or contraction of a given metal is a function of the f a)-density b)-initial temperature c)- temperature difference d)- linear coefficient of thermal expansion e)- final temperature f)- original length

Vibration monitoring this technique uses the noise or vibration created by mechanical equipment and in seme cases by plant systems to detemine their actual condtion. a)- true b)- false
