g column of sand has water flowing through it. At the left end of the column, the pressure is 37,470 Pa, and the elevation is 0.310 m. At the right end of the column, the pressure is 26,820 Pa, and the elevation is 0.260 m. The permeability of the sand is 2.07 x 10-13 m2. The internal diameter of the column is 0.0100 m, and the column is 1.05 m long. Total porosity is 0.21. Effective porosity is 0.18. How long will it take for a sorbing tracer with R

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?

Water at 55c flows across a flat plate whose surface temperature is held constant at 95c. if the temperature gradient at the plate's surface for a given value of x is 18 c/mm, find a) local heat transfer coefficient. b) heat flux

True or false (explain) (110)[111] is a slip system in bcc metals . the {111} family in fcc contains 8 planes. resolved shear stress (rss) in single crystals is just related to the applied stress. critical resolved shear stress (crss) in single crystal metals is direct proportional to the number of defects in the structure
