Ashock wave is moving at a mach number of 3 into undisturbed air (t=20ºc and p=101.3 kpa). what are the velocity and stagnation temperature (with respect to a stationary observer) of the air after the passage of the shock wave? also find the static pressure and temperature and stagnation pressure (relative to a stationary observer) after the shock passage.

For each of the following process: a) sketch the p-v diagram, b)sketch t-s diagram, c) sketch t-v diagram, d) sketch the boundary work on one of the diagrams (a, b or c) and e) sketch the reversible heat transfer on one of the diagrams (a, b or c): 1- isobaric process from compressed liquid to superheated vapor 2- isothermal process from compressed liquid to superheated vapor 3- isentropic process from compressed liquid to superheated vapor
