Provide a reasonable design for a 99.4% efficient esp treating 30,000 m^3/min of gas. the dust has a resistivity of 7.1 (10)^10 ohm-cm. specify the total plate area, channel width, number and size of plates, number of electrical sections (total and in direction of flow), and total corona power to be supplied, and estimate the overall dimensions.

Inspection for bearing condition will include: (clo4) a)-color b)-smell c)-size d)-none of the above

10 kg of co2 is initially contained at 400 kpa and 300 k. the gas constant for carbon dioxide is 189 j/lkg k) and has a specific heat ratio, k, of 1.289. isentropic expansion then occurs until the pressure is 200 kpa. a) determine the initial volume of co2 in m. b) determine the final temperature in k. c) determine the work done by the system during the expansion kl.

For a process taking place in a closed system containing gas, the volume and pressure relationship is pvi-constant. -1.5 bar, the process starts with initial conditions, pi = =0.03 m3 and ends with final volume, v2-0.05 m3 determine the work done by the gas.
