A gas-powered forklift emitting 8 mg/s of non-reactive CO is driven continuously across a 5.0 104 m3 warehouse ventilated at a rate of 3.0 m/s. The intake air has a CO concentration of 10 mg/m? Which schematic is the correct depiction of the problem? ain -3.0 m3/s V = 5.0 104 m3 Qout = Qin = Cin = 10 mg/m3 E = 8 mg/s Cout #c V = 5.0 104 m3 Qin - 3.0 m3/s Qout = Quin = C Cin = 10 mg/m3 = E = 8 mg/s Cout = C = = Cin1 = 10 mg/m3 Qin1 = 3.0 m/s = V = 5.0 104 m3 Qout # Qin C = Qin2 = 3.0 m3/s E = 8 mg/s Cout # C - = bout = Qin Cin1 = 10 mg/m3 Qin1 = 3.0 m/s V = 5.0 104 m3 C Quinz = 3.0 m/s E = 8 mg/s Cout = C A Pt/Al2O3-based emission control system modeled as a PFR is added to the forklift. The emission control system oxidizes CO into CO2 (a harmless gas) at a first-order rate k = 1 5-1. What is the volume of the PFR (in m3) required for the forklift to reduce its emission by 50%
