1. The organic carbon adsorption data given below were obtained using two activated carbon samples, A and B. In each case 1.0 g of carbon and a liquid volume of 1.0 L were used. Determine the appropriate model to be used in each case. Initial Concentration Equilibrium Concentration, g/m3
g/m3 A B
1.0 0.010 0.053
2.0 0.020 0.124
4.0 0.040 0.290
8.0 0.081 0.677
16.0 0.165 1.58
32.0 0.344 3.67
64.0 0.751 8.52
128.0 1.843 19.66
2. A secondary wastewater effluent having a total organic carbon (TOC) concentration of 12 g/m3 is to be treated further by activated carbon adsorption. The objective is produce water having no more than 1.0 g/m3 TOC. Determine the amount of a carbon that would be necessary per cubic meter of secondary effluent if the carbon characteristics were those of (a) carbon A in Part 1 and (b) carbon B in Part 1. Assume the system is a batch process.

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?
