The town of camp verde has been directed to upgrade its primary wwtp to a secondary plant that can meet an effluent standard of 25.0 mg/l bode and 30 mg/l suspended solids. they have selected a completely mixed activated sludge system for the upgrade. the existing primary treatment plant has a flow rate of 2,506 m3/d. the effluent from the primary tank has a bod5 of 240 mg/l. using the following assumptions, estimate the required volume of the aeration tank: 1. bod5 of the effluent suspended solids is 70% of the allowable suspended solids concentration. 2. growth constant values are estimated to be: ks =100 mg/l bod5; kd =0.025 d^-1 μm=10d^-1; y= 0.8mg vss/mg bod5 removed.3. the design mlvss is 3,000 mg/l.

Refrigerant 134a enters an insulated compressor operating at steady state as saturated vapor at -26°c with a volumetric flow rate of 0.18 m3/s. refrigerant exits at 9 bar, 70°c. changes in kinetic and potential energy from inlet to exit can be ignored. determine the volumetric flow rate at the exit, in m3/s, and the compressor power, in kw.
