Inlet stagnation air pressure of a two-dimensional compressor cascade is 1.0 bar and inlet stagnation temperature of 295k. for an inlet mach number of 0.75 and an inlet flow angle of 48°, the exit flow angle is measured as 16.5°. assuming the flow is isentropic, determine the mass flow rate per unit frontal area, the exit mach number and the static pressure ratio across the cascade.

On a average work day more than work place firs are reorted

Afluid flows with a velocity field given by v=(x/t)i.. determine the local and convective accelerations when x=3 and t=1.

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?
