You are designing a reactor that uses chlorine in a PFR of CMFR to destroy pathogens in water. A minimum contact time of 30 mins is required to reduce the pathogen concentration from 100 pathogens/L to below 1 pathogen/L through a first order decay process. You plan on treating water at a rate of 1,000 gal/min.
A) what is the first order decay constant?
B)What is the minimal size (in gallons) of the reactor required for a plug flow reactor?
C)What size (in gallons) of CMFR would be required to reach the same outlet concentration
D) Which reactor requires the least Volume? Briefly explain why the PFR and CMFR volumes are different for achieving the same degree of pathogen reduction.
E) If the desired chlorine residual in the treater water after it leaves the reactor is .20mg/L, and the chlorine demand used during treatment is.15mg/L, what must be the daily mass of chlorine added to the reactor in grams?
Estimate the machines production under these conditions using the travel time curves given in the Caterpillar Performance handbook.
Which software do we use to calculate force and moment, and draw shear and moment diagram? I really need this software to design my structural project. Please helps me... thank you so much
A machine is supported on four steel springs for which damping can be neglected. The natural frequency of vertical vibration of the machine-spring system is 200 cycles per minute. The machine generates a vertical force p(t)=p0sinwt.
A soil sample with a volume of 0.5 m3, dry unit weight = 18.1 kN/m3, water content = 5%, and Specific Gravity of the soil solids = 2.68. Calculate weight of water added to reach 90% saturation (in kilograms)?
The linkage shown is made up of two 3-kg rectangular members (0.4 m by 0.1 m), and is flying through the air. At the instant shown, the vertical member has angular velocity 4 rad/s, and the angled member has angular velocity 1 rad/s.
Given the total dissolved solids in a brine is 20,500 ppm, compute the resisitivity at a reservoir depth of 8,000 feet.
A soil has a total density of 1.80 Mg/m3. When fully dry, the soil has a density of 1.59 Mg/m3. The specific gravity of the solids is 2.57. Find the following soil parameters: a) Dry unit weight of the sample
A sample of neon has a volume of 555 mL when it is at a pressure of 813 mmHg. What will be the volume when the pressure is increased to 1138 mmHg?
A wheel has an angular acceleration of alpha=(0.5*theta) rad/s^2 , where theta is in radians. a) Determine the magnitude of the velocity of point P located on its rim after the wheel has rotated 2 revolutions.
We would continue embankment work even if winter season and my question is what is swelling amount of compacted soil for 30cm thickness and 95% compaction degree by freezing.
After initial mixing, the DO concentration in the river is 9.5mg/L and the temperature is 15ºC. If the ultimate BOD of the mixed river water is 30mg/L,
Find the discharge flowing over a rectangular sharp crested wire, in GPM, which has a width of 9.9 feet and a discharge coefficient of 3.24, if the head above the crest is 1.74 feet.
