1. A completely mixed continous bioreactor used for growing oenicilin operates at a zero orer system. The input glucose is converted into various organic yeats. the flow rate ti this system is 20 liters per minute and the conversin rate is 4 mg/(min- L). The influent glucose concentration is 800 mg/L and the effluebt must be less than 100 mg/L. What is the smallest reactor capable of producing this cinversion?
2. A completely mixed flow reactor operating at steady state has an inflow of 4 L/min and an inflow gloop concentration 400 mg/L. The volume is 60 liters; the reaction is zero order. The gloop concentration in the reactor is 100 mg/L.a) what is the raction rate constant?b) what is the hydraulic reaction time?c) What is the outflow (effluent) gloop concentration
An equal tangent vertical curve connects a -2% and a +3% grade. The low point of the curve is at elevation 297.88 ft. If the PVI is at elevation 295 ft, what is the design speed of the curve
The linkage shown is made up of two 3-kg rectangular members (0.4 m by 0.1 m), and is flying through the air. At the instant shown, the vertical member has angular velocity 4 rad/s, and the angled member has angular velocity 1 rad/s.
