For the flow of a thin film of a liquid with a depth h and a free surface, two important dimensionless parameters are the Froude number, VVggh⁄, and the Weber number, VV2hσσ⁄. Determine the value of these two parameters for glycerin (at 20 C) flowing with a velocity of 0.7 m/s at a depth of 3 mm

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?
