Backriver wastewater treatment plant must disinfect its effluent before discharging the wasterwater onto Backriver. The plant has plug flow reactor of length 1800m which treats the wastewater biologically by first order reaction with decay at a rate constant of 0.20h^-1. The wastewater influent has a linear velocity of 0.5m/s and contains 3.0x10^5 fecal coliform colony unit (CFU) per liter. Determine the coliform concentration of the discharge effluent into Back river.
atmospheric air at 1.01 bar 30 c and 60 percent relative humidity flows over a set of cooling coils at an inlet flow rate of 1500 m^3/min the liquid which condeness is removed from the system at 17 c
an investment of $80,000 is projected to generate escalated dollar net revenues (income minus costs) of $10,000 in year one, $30,000 in year 2 and $40,000 in year 3 with a $100,000 salvage value at the end of year
assume the drop has the shape of a hemisphere just before seperating. find an expression for the diameter, D, of the droplet, in terms of the specific weight and surface tension, assuming the contact angle just before seperating is zero.
The air pressure is 120 KPa, the air temperatuer is 28 degrees C, and the dew point is 20 degrees C. Calculate the corresponding vapor pressure (ea) and relative humidity (RH). Assume Atmospheric pressure is 101,000 Pa.
The temperature was 200C, and the void ratio (e) of the soil was 0.43. Calculate the "Coefficient of Permeability" in "centimeters per second" (Given, k = (QL)÷(A Δh t)).
