Calculate the following values for each process to meet the 10 State Standards. • Primary clarifier: determine diameter, hydraulic loading rate, Vo; detention time, t; weir loading rate, W; BOD concentration. • Aeration tank: determine the length & width, hydraulic loading rate, Vo; BOD loading rate. • Secondary clarifier: determine diameter, hydraulic loading rate, Vo; detention time, t; weir loading rate, W; final BOD removal efficiency in a percentage. Then, design the plant layout to scale. In addition to the primary clarifier, aeration tank and secondary clarifier the following structures are to be included. Make every effort to layout the structures in the order of the wastewater treatment process so that there is minimal piping between processes. • The total footprint of the plant shall not exceed the lot size of 400ft x 600ft. • The administrative building is 100ft x 50ft on the lot. • The service building is 200ft x 150ft on the lot. • Roadways between each process shall be 12ft minimum to allow for vehicular access. • The preliminary bar screen/grit chamber building is 50ft x 50ft. • There are 2 chlorine contact buildings with dimensions of 25ft x 50ft each. • There are 2 sludge digesters with dimensions of 50ft diameter each.

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?
