4. Consider that we have a watershed with area of 1000 km2 with no rain gages, but there is a gaged stream at the watershed outlet that averages 15 m3/sec. a) what is the total volume of water flowing out of the watershed over one year; b) assuming 40% of all precipitation is lost to evapotranspiration and infiltration, what is the estimated depth of precipitation over the watershed in one year.

If the thermal strain developed in polyimide film during deposition is given as 0.0044. assume room temperature is kept at 17.3 c, and thermal coefficient of expansion for the film and the substrate are 54 x 10^-6c^-1 and 3.3 x 10^-6c^-1respectively. calculate the deposition temperature.

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?

Draw the engineering stress-strain curve for (a) bcc; (b) fcc metals and mark important points.
