- 5.15. A small-parts assembly line involves the use of solvents requiring a high level of ventilation. To achieve removal of these toxic gases, a mean velocity of 8 ft/s must be maintained across the cross-section of a 12 ft high by 30 ft wide room. The toxicants are subsequently removed in a wet scrubber or filter, which causes a pressure drop of 30 lb/ft². Using a Cordier analysis, select the design parameters for a fan that will provide the required flow and pressure rise, while oper ating at or near 90% total efficiency, and that minimizes the diameter of the fan. Give dimensions and speed of the fan and describe the type of fan chosen.As an environmental engineer working for a consulting company you were asked to evaluate an existing water treatment plant for possible upgrade. One of the treatment unit processes you evaluated was the rapid mix tank. You had the following information. 2. Current average water flow rate 15 x 10' m'/d. Projected flow rate in 20 years 24 x 10' m'/d. Temperature of water varies from 12 to 20° C. No. of rapid mix tank = 1 Dimension of tank: water depth 2.1 m, width 2.1 m, length 2.1 m Tank is not baffled: Mixer is 4-bladed turbine with 45° pitched blade (N, = 1.27) Diameter of impeller 0.9 m Label on the motor: horsepower of motor 10 hp (1 hp 746 watts) rpm of blades = 120 rpm (assume a motor efficiency of 80%) Evaluate whether the rapid mix system (1) Is sufficiently designed for current use? If not, provide some remedies. (i) Will the current system be sufficient for the projected flow rate in 20 years? If not, what are some of your suggestions or additions to meet the projected flow?he night-time chilled water system is not a closed loop system, meaning that some amount of water is lost due to evaporation every night. If it is 96% efficient (i.e. 4% of the water flow rate is dispersed to the outdoor air and needs to be replaced), how much make up water does it need to draw from the municipal water supply daily (in gallons)? Round to nearest integer. (Given: Qheat loss = 1,500,000 Btu) Total gallons in water tank: 1500 gallons//system runs: 10 hours

The cylindrical fin has a diameter of D 20 mm, and cross-sectional area is the same for each configuration shown in the sketch. V, T, V, T, V, T. Configuration A Configuration B Configuration C For fins of equal length and therefore equal mass, which fin has largest heat transfer rate? %3D Assume the gas properties are those at T (treat it as air) = 350 K. Hint: Assume the fin can be treated as infinitely long. D Focus stes)2. A water treatment plant has 6 settling tanks that operate in parallel (the flow gets split into six equal flow streams), and each tank has a volume of 600m3. If the flow to the plant is 10 mgd, what is the retention time in each of the settling tanks? If, instead, the tanks operated in series (the entire flow goes first through one tank, then the second, and so on), what would be the retention time in each tank?Please solve question A7.4, Thank You!
