a. Calculate the dry air and water vapor mass flow rates (lb/min) if the volume flow rate is 1,000 cfm, the humidity ratio is 0.025 lbv/lba, and the dry air density is 0.072 Iba/ft3. b. Assume the above air enters an evaporator coil at 90°F where it is cooled in a constant humidity ratio process until reaching the 100 % RH curve ( the temperature at that point is the dew point. The air then keeps dropping in temperature, following...

*Explanations should be brief. Draw a box around each final answer, if applicable.* 1. Consider intermolecular forces and kinetic energies with respect to a solid and a liquid. Explain why molecules in a liquid are free to move past each other, while molecules in a solid are held in fixed positions. 2. Use your knowledge of intermolecular forces to provide an explanation for why the boiling point of 2-hexanol is higher than the boiling point of 2,3-dimethyl-2-butanol. Be sure to...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
