Use diffusion theory to estimate light penetration in biological tissues. A 10-mW isotropic point source is buried in an infinite turbid medium. Assume that the absorption coefficient is 0:1 cm-1, the scattering coefficient of a 5-cm thick tissue is 100 cm-1, the scattering anisotropy is 0.9, and the wavelength of light is 0:5 mm. Calculate the light fluence rate 5 cm from the source.
The azeotrope contains 61mole % CS2. Estimate the work of separation if the feed solution is liquid at 39.250C and the products are withdrawn at the same temperature. At 39.250C, 1 2 604 ; 400 . S S P mmHg P mmHg?
