The flow is turned using a compression ramp and an expansion corner. if the approach flow mach number is, m=3, approach flow static pressure is, p1=1 atm, and the ramp angle is 10 degrees, a) (10 pts) calculate the mach number after the compression ramp. b) (10 pts) calculate the flow turning angle, t, required to achieve m=3 after the expansion corner. c) (10 pts) calculate the total pressure after the compression corner. d) (10 pts) calculate the static pressure after the expansion corner.

The mass flow rate of the fluid remains constant in all steady flow process. a)- true b)- false

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?

Describe one experiment in which the glass transition temperature and melting temperature of a totally amorphous thermoplastic material can be determined. show the relevant experimental results in a diagram which should be properly annotated with the two temperatures clearly marked. what is likely to happen to the curve in the diagram if the amorphous polymer is replaced by a thermosetting type?
