## Question: Design an air stripping column to remove TCE from water (i.e. determine the stripping factor, the height and number of transfer units, and the height of the packing in the column). The initial concentration of TCE is 1.3 mg/L and this must be reduced to 75 μg/L. Use the following criteria: water flow rate of 350 gals/min; air to water ratio of 70; water temperature of 16⁰C; air temperature of 23⁰C; column diameter of 2 ft; 2-in Intalox saddles for packing material; liquid mass transfer coefficient of 20.4 cm/hr; design safety factor of 20%; and tower height(s) between 1-15 m. -Free Course Hero Question Answer.

## Question: Problem 12.3) The project is in a low-silica marble formation. Company drilling experience in this area indicates that compressed-air rotary-percussion drills with 3-in. button bits can average 2.2 ft of penetration per minute. Assume that it takes 3 min to change a bit. Drilling efficiency is typically a 45-min hour. These drills use 10-ft drill steel. The best blasting pattern is 8 ft x 9 ft with 1.5 ft of sub drilling. The average excavation depth is 12 ft. How many drills will you recommend for use on the job? -Free Course Hero Question Answer.
