Rainfall rates for successive 20-minute periods of a 140-minute storm are 1.5, 1.5, 6.0, 4.0, 1.0, 0.8, and 3.2 inches/hour, totaling 6.0 inches. determine runoff during successive 20-minute periods by the nrcs method (i. e. curve number method). the soil in the basin belongs to group a. it is an agricultural row cropland with contoured pattern in good hydrologic condition.

Thermal stresses are developed in a metal when its a) initial temperature is changed b) final temperature is changed c) density is changed d) thermal deformation is prevented e) expansion is prevented f) contraction is prevented

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?

You are making beer. the first step is filling the glass carboy with the liquid wort. the internal diameter of the carboy is 15 in., and you wish to fill it up to a depth of 2 ft. if your wort is drawn from the kettle using a siphon process that flows at 3 gpm, how long will it take to fill?
