You find that the threads in a hole are damaged and try to use a tap to repair them. You find that there is not enough material left to repair the threads. What would be the best solution to your problem and why?

Explain the difference laminar and turbulent flow. explain it with the shear stress and the velocity profiles.

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?
