Two rectangular clarifiers(sedimentation basins), each 30 ft long, 15 ft wide, and 10ft deep, settle a combinedtotal of 0.40 mgd following alum coagulation. The effluent channelshave a total weir length of 60ft in each basin. Calculate the detention time (in hours),horizontal velocity of flow (ft/min), and rate offlow over the outlet weir (weir loading, in gpd/ft).
average flow rate = .0022 m^3 /s (190 m^3 /d) Influent Substrate concentration = 250 mg/L as COD (all essentially soluble) Mean cell residence time is to be 5 days Volume of mix tank = 25 m^3 the reactors kenetic constants are
Compute the amount of chlorine required for disinfection in pounds per day(lb/d). Estimate the annual cost for disinfection using chlorine. Flow Rate= 30 milloin gallons per day.
Write a computer program that can be used to determine the internal shear and moment at any specified location x along the beam, and plot the shear and moment diagrams for the beam.
An experiment was conducted to determine the hydraulic conductivity of an artesian aquifer. The piezometric heads at two points 150m apart were found to be 55 m and 48.5 m above a datum.
The 20-lb cart B is supported on rollers of negligible size. If a 10-lb suitcase A is thrown horizontally on it at 10 ft/s, determine the length of time that A slides relative to B, and the final velocity of A and B. The coefficient of kinetic fri..
A tidal channel, which may be assumed to be rectangular, is 40 m wide and conveys a discharge of 60 m3/s at a depth of 1.52 m. A tidal bore is seen to propagate upstream with a wave speed of 5 m/s.
The road is in good condition and is initially dry, but it becomes wet 160 ft before the stalled car (and stays wet until the car is reached). What is the minimum distance from the stalled car at which the driver could apply the brakes and still s..
To be sure that the part does not fail, we plan to ensure that the maximum applied stress is only one third of the tensile strength. We use a non-destructive test that will detect any internal flaws greater than 1.25 mm long.
Calculate the drawdown at the well (use r which is the distance from the pumping well = 18 in) with total withdrawals from storage after (a) 1 min, (b) 1 h, (c) 1 day, (d) 1 month, and (e) 1 yr of continuous pumping, at design capacity.
investing in the General Motors costs $10,000 today and pays back $11,500 two years from now. If investing in the Ford costs $8,000 today and pays back $4,500 each year for two years, which alternative is inferior
A fluid flows into a plug flow reactor of volume, V, with volumetric flow rate, Q. Inflow contains species A and B and concentrations A0 and B0. Within reactor, species A undergoes first order reaction producing B... R=k[A].
Determine the degree of saturation of a sample of soil given that its maximum dry unit weight is 18 kN/m^3 and its optimum moisture content is 12.1%. Assume the Specific Gravity of soil is 2.65.
