A complete-mixed suspended growth reactor, without a clarifier and recycle, is used to treat flow containing only soluble organic substances. The influent BOD and COD are as follows:Influent BOD: 200 mg/L and COD: 450 mg/LIf the effluent dissolved BOD concentration is 2 mg/L, and the effluent volatile suspended solids concentration is 100 mg/L, please determine:a. The observed yield in terms of g VSS/g BOD, g VSS/g COD, b. The effluent total sCOD concentration including nonbiodegradable dissolved CODc. The fraction of the influent BOD that is oxidized to CO2 and H2OAssume the biodegradable COD/BOD ratio is 1.6 and 1.42 g O2 equivalent/ g biomass.

Air is to be cooled in the evaporator section of a refrigerator by passing it over a bank of 0.8-cm-outer-diameter and 0.4-m-long tubes inside which the refrigerant is evaporating at -20°c. air approaches the tube bank in the normal direction at 0°c and 1 atm with a mean velocity of 4 m/s. the tubes are arranged in-line with longitudinal and transverse pitches of sl- st 1.5 cm. there are 30 rows in the flow direction with 15 tubes in each row. determine (a) the refrigeration capacity of this system and (b) pressure drop across the tube bank. evaluate the air properties at an assumed mean temperature of -5°c and 1 atm. is this a good assumption?
