A factory disposes 1.1 m3/s of treated industrial wastewater into a river. The wastewater has an ultimate biochemical oxygen demand of 25 mg/L and dissolved oxygen of 2 mg/L. Just upstream of the wastewater outfall, the river has a flow rate of 10 m3/s, ultimate biochemical oxygen demand of 6 mg/L, and oxygen deficit of 2 mg/L. At the river temperature, the saturation concentration of dissolved oxygen is 9 mg/L. The deoxygenation coefficient is 0.19 d-1 and reaeration coefficient is...

The decomposition of sodium azide (NaN3) is often used to inflate car airbags. A possible balanced chemical reaction for this decomposition reaction is 6 NaN3(s)+ 2 Fe2O3(s) = 3 Na2O2(s) + 4 Fe(s)+ 9 N2 (g). What volume of nitrogen can...

1.7 kg/s NH3 and 20 m3/s air at 25 oC and 1 atm are fed into a reactor in which the ammonia is completely consumed. The product gas emerges at 300 oC. Calculate the rate at which heat must be transferred to or from the reactor, assuming operation at approximately 1 atm. You must show full systematic working. The standard heat of reaction for the oxidation of ammonia is given below: 4 NH3(g) + 5 O2(g) ? 4 NO(g) +...

Water flows in a horizontal pipeline at a steady flow rate of 0.03 m3 s-1. The pipeline terminates with a reducing bend that deflects the water upwards at an angle of 45 degrees, as shown in Figure QB2. The water issues into the atmosphere. The area of the pipe is 150 x 10-4 m2 and the area at the exit to the bend is 25 x 10-4 m2. The gauge pressure at the inlet to the bend is 73.9 kN...
