How can we increase collection efficiency in electrostatic precipitation?

Describe about the Penetration resistance values for which liquefaction is unlikely to occur under any Conditions.

What are the time related disoutes?

A groundwater borehole at USM engineering campus contains 3000 mg/L of TDS. The flow is 0.32 m³/s. The design TDS concentration of the product water is below 400 mg/L. The net pressure is 40 atm. The membrane manufacturer provides that the membrane has a water flux rate coefficient of 2.2 x 10-6 s/m and a solute mass transfer rate of 1.5 x 10-6 m/s. Calculate the membrane area required for the RO system.

For an electrostatic precipitator of given geometry and operating conditions, the collection efficiency for 2 micrometer particles is 99.90 percent. On the basis of a Deutsch-type equation for efficiencies, estimate the collection efficiency for (a) 1 micrometer and (b) 0.5 micrometer particles

How long would it take for chloride to be detected just outside the clay liner at the secondary MCL of 250mg/L? Assume diffusion is the only mechanism

solve question 10 please

What diameter would a circular clarifier have to be to remove 50 μm particles with 75% efficiency from a 4 MGD (million gallon per day) flow?  Assume the particle specific gravity is 1.5 and the temperature is 10°C.  Answer: 18 m

i need ans very fast in 20 min please

Estimate the terminal settling velocity in water at a temperature of 15°C of spherical silicon particles with specific gravity 2.4 and average diameter of 0.05mm. Assume p=999 kg/m3 and p= 0.00113 Ns/m2
