Design two circular primary clarifiers with effluent weirs installed in the periphery of the tank to treat a wastewater flow of 12900 m3/d. Calculate the weir loading rate and hydraulic detention time. Assume the clarifiers having a 2 m side water depth (Assuming the desired overflow rate = 20 m3/m2×day).

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?
