2. Assume that the river has been selected as the source of raw water for the 2.0mgd demand.
a. Surface water has low alkalinity, high turbidity. The distribution system is cast iron pipe. What's the concern with using alum (Al2(SO4)3) as the coagulant. What other chemical could be used?
b. A slow sand filter will follow the coagulation-flocculation-sedimentation. The organic content in the raw water supports a biofilm on the filter surface. How might this reduce the disinfectant dosage? What text Figure shows this?
c. The 4' thick filters run q=500 gpd/ft2. Find the total area of filter surface required to treat the 2.0 mgd. Also compute the hydraulic residence time in the filter.
d. The filtered water still has traces of ammonia and dissolved organics. Calcium hypochlorite Ca(OCl)2 is used for disinfection. What's the advantage, what's the potential problem with using the hypochlorite rather than using ultraviolet (UV)?
explain ways of representing alternative quantities;1)phasor representation 2)graphical representation 3)complex waves 4)addition and subtraction of sine wave
how much of mass lost in between 600-900 c
Q. A steel bar 10 cm broad and 8 mm thick is subjected to bending moment. The radius of the neutral surface is 100 cm. Found out the maximum and minimum bending stress in beam.
Determine moment of this normal force - rectangular beam: A rectangular beam contains a width of 100 mm and a depth of 200 mm. This is utilized as a simply supported beam & th
calculate stress intensity factor
Forces working on dam: Let a dam retaining water as illustrated in Figure (a). What are the forces working on it? Solution The forces working on dam are as follows:
Industrial Manufacturing Activity can broadly be divided into the followings ways: Mass Production Large lots e, g, Automobiles : In this the volume of production is very hi
