Consider a small diffuse surface of area A1 = 1 cm2 with a total emissive power of 50000 W/m2. Another small surface of area A2 = 5 cm2 is located at a distance of r = 50 cm from A1 at an angle of θ1 = 60° w. r.t to the normal of A1. The line joining the two surfaces is at an angle of θ2 = 30° w. r.t to the normal of A2.

Water in a partially filled large tank is to be supplied to the roof top, which is 8 m above the water level in the tank, through a 2.2-cm-internal-diameter pipe by maintaining a constant air pressure of 300 kpa (gage) in the tank. if the head loss in the piping is 2 m of water, determine the discharge rate of the supply of water to the roof top in liters per second.

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?
