A pond with a single inflow has the following characteristics:
Mean depth = 3 m
Surface area = 2 * 105 m2
Residence time = 2 weeks
Inflow BOD concentration = 4 mg/L
A small village of 1000 people will discharge their raw sewage into this system. Each individual contributes about 600 L/person/day of wastewater and 0.125 gr/person/day of BOD.
Determine the BOD concentration in wastewater in mg/L.
If BOD decays at a rate of 0.1 day-1 and settles at a rate of 0.1 m/day, calculate the assimilation factor for the pond prior to building the village.
Calculate transfer function factor after building the c.
Determine the steady state concentration of BOD for the lake with and without the village.
Assume the plane is flying at an altitude of 32,810 ft (10 km), where the temperature is -8 C and the pressure is 250 mb. The Pitot-static tube measures a piezometric pressure difference corresponding to 1.206 psi. What is the airspeed in both m/s..
The Washington Monument is 169 m tall. What is the stress in the lowermost rock if it is made of Georgia granite?
A dam located in a channel of rectangular cross-section which carries water flowing at a rate of 8.75m3/s. The depth of water upstream of the dam is 2.5m. the channel is 5m wide,
determine the width of the flume to be used such that the depth of flow immediatly upstream of the throat under design conditions is 1 m. By what percentage is the capacity of the flume reduced if the downstream depth is 0.85m
Use the strain-transformation equations to determine (a) the in-plane principle strains and (b) the maximum in-plane shear strain and average normal strain.
determine the magnitude Fs of the tensile spring force in order that the resultant of Fs and F is a vertical force . Determine the magnitude R of this vertical resultant force.
determine the elastic elongation that would be expected for a 16-mm-diameter rod of the same material if the rod were 1.6 m long and subjected to a tension force of 3.3 kN.
The thermocouple effective diameter is 2 mm and it is exposed to a convection environment at 20? with h = 125 W/m2 · ?C. The convection coefficient to the solid is 15 W/m2 · ?C. The thermocouple indicates a solid temperature of 125?C. Calculate the t..
Determine the tributary widths and tributary areas of the joists, beams, girders and columns in the roof framing plan
Determine the change in dilation angle between the two tests, if a CD test were carried out.
a 3000 lb car has a maximum speed of 140 mi/h with 16-in radius wheels, a gear reduction of 3.5 to 1, and a drivetrain efficiency of 92%. it is known that at the cars top speed the engine is producing 220 ft-lb of torque.
A square with the dimensions of .02m by .02m by .5m is attatched to a solid surface. If the forces on the rod are too large, it will either crush or be sheared off where it is atatched to the solid surface.
