The Mach number distribution in a shear layer of air is measured by a "pitot-rake" as shown below.
static pressure in the slow moving layer is 10 psia.
Calculate the Mach number M1 thru M4 in the shear layer when the
Po4 = 50 psia
Po3 = 28 psia
Po2 = 17 psia
Po, = 13 psia

Consider a large isothermal enclosure that is maintained at a uniform temperature of 2000 k. calculate the emissive power of the radiation that emerges from a small aperture on the enclosure surface. what is the wavelength ? , below which 10% of the emission is concentrated? what is the wavelength ? 2 above which 10% of the emission is concentrated? determine the wavelength at which maximum spectral emissive power occurs. what is the irradiation incident on a small object placed inside the enclosure?
