The mass concentration in mg/L of a carbon compound (C6H12O6N2) measured in a water sample is three times higher than NH3 mass concentration. The ThOD for both carbon and nitrogen oxidation are 384 mg/L. What is the concentration of NH3 (mg/L) in water sample? (Molecular weight: C6H12O6N2= 208; NH3 = 17; O2 = 32) Assume, NH3 concentration = x mg/L C6H12O6N2 concentration = 3x mg/L NH3 C6H12O6N2 + O2 NH3 + O2 + + CO2 + H2O + NO3 + H + H20

Asingle-geared blanking press has a stroke of 200 mm and a rated capacity of 320 kn. a cam driven ram is assumed to be capable of delivering the full press load at constant force during the last 15 percent of a constant-velocity stroke. the camshaft has an average speed of 90 rev/min and is geared to the flywheel shaft at a 6: 1 ratio. the total work done is to include an allowance of 16 percent for friction a) estimate the maximum energy fluctuation b) find the rim weight for an effective diameter of 1.2 m and a coefficient of speed fluctuation of 0.10

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?
