Four liters of water are equilibrated with a gas mixture containing carbon dioxide at a partial pressure of 0.3 atm. Henry's law constant for H2CO3* solubility is 2.0g/L-atm.
a) How many grams of CO2 are dissolved in the water? What is the pH of this water? (neglect secondary dissociation of carbonic acid.)
b) Assume that H2CO3* dissolves first without dissociating, achieving equilibrium with the atmosphere, and then the solution is closed to the atmosphere. H2CO3* then dissociates (neglect secondary dissociation). Find the pH of this solution and compare it to the result obtained in (a).
The wastewater treatment plant for Pine City discharges 1 × 105 m3/day of treated waste to the Pine River. Immediately upstream of the treatment plant, the Pine River has an ultimate CBOD of 2 mg/L and a flow of 9 × 105 m3/day.
My question is regarding UVA levels in raw and treated drinking water with regard to TOC and DOC removal. Is there a jar test procedure that incorporates the UVA values of the various stages of treatment and is there a document you could refer me ..
The channel entrance is rounded and smooth (negligible head loss at entrance), and the reservoir water surface is 2.5 m above the bed of the channel at the entrance. hf=0.00019*Q2, where Q (in m3/s) is the discharge in the channel.
A trapezoidal channel has a bed width of 3.5 m and a side slope of 30 degrees from the horizontal. Determine the critical depth and the critical velocity for a flow of 22 cubic meters per second.
The number of parking tickets issued in a certain city on any given weekday has a Poisson distribution with parameter = 50. What is the approximate probability that 1 between 35 and 70 tickets are given out on a particular day
determine the magnitude of the resultant force and its direction, measured counterclockwise from the positive axis. The other force is F=700N with a 15 degree angle to the x-axis.
A smooth hump is placed in the bottom of the channel. What would be the depth of flow over a 3 ft high jump. How high can the hump be made without backing flow up What would be the depth of flow over and just upstream of a 6 ft high jump
Assume that the sludge does not change density during filtration and that liquid removed from the sludge contains no sludge. Using mass-balance method. determine the volume of sludge after filtration.
During a 108 minute long storm, the precipitation rate over a 100 acre area is 1.65 in/hr. The phi index is 0.42 in/hr. The average outflow from the area is 92 cfs during the storm. What is the value of combined detention and interception storages ..
A reinforced concrete beam having the cross section shown is on a simple span of 28ft. It carries uniform service loads of 3.60 kips/ft live load and 2.20 kips/ft dead load. Check the adequacy of the beam with respect to the moment.
One method of removing phosphate from wastewater effluents is to precipitate it with aluminum sulfate. A plausible stoichiometry (but not exact because aluminum and phosphate can form many different chemical materials) is
Assuming Stokes behavior, calculate the terminal settling velocity in standard air for the following particles: (a). diameter = 10 micrometers, specific gravity =1.2; and (b) diameter = 4 micrometers, specific gravity = 2.0.
