Determine the volume of water lost (in m3) through evaporation during a year from Lake Okeechobee (Florida). Lake Okeechobee has a surface area of 190,000-ha located in a region where the annual rainfall is 1500 mm. The increase in the depth of the lake over the year is 18 cm. Neglect the effect of groundwater flow. Report the final answer with 2 significant digits.
A bridge has been constructed between the mainland and an island.The total cost (excluding tolls) to travel across the bridge isexpressed as C = 50 + 0.5V, where V is the number of veh/h and C isthe cost/vehicle in cents.
The bottom of a triangular channel is designed to be the best hydraulic section for critical flow at a depth of 1.25m; the sidewalls above the bottom section are vertical and the same width as the triangular section.
The mine's operating costs were projected at $900,000 per year including $400,000 of fixed costs and $500,000 of variable costs. Ms. Peru thought these forecasts accurate.
A well mixed sewage lagoon is to be constructed to process 100000 gallons per day of raw sewage. The pollutant concentration in the raw seweage to be discharged into the lagoon is 200ppm. the organic matter in the sewage has been shown in a laborator..
Consider the two loading scenarios on the beam, where the beam is supported by a pin joint on the left and roller joint at the right end. What are the internal forces and moment at point A for each scenario
If the stage of a stream increases by 40% and the slope of the water surface becomes half of its original slope, then what will be changes in discharge of the stream
Compute the magnitudes of the normal stresses (sigma,x) and (sigma,y) in front of a surface crack of length 2.0 mm in response to a nominal tensile stress of 100 MPa at the following positions:
Iron can exist in the FCC or BCC structure. For FCC iron, the crystal lattice parameter is a=0.3515nm and the atomic packing factor is 0.74. In an FCC structure, iron atoms have an atomic radius of 0.1263nm.
Ozone is sometime used as a disinfectant for drinking water. Ozone is highly reactive it will react benign species found in water, as well as the pathogens it is intended to kill.
Some organisms live in shallow ponds, where much of the water will evaporate during the warm, sunny, summer months. How will the concentration of solute change in the water druing this time? Will this create problems for the organims in the pond wate..
If the mean and variance of discrete random uniform random variable X, are E(X) and V(X) respectively, what would the mean and variance of cX be in terms of E(X) and V(X) if c is a constant
Consider a piston/cylinder arrangement that has a linear spring mounted such that as the piston rises to a certain point it will encounter the spring, which will offer a downward component of force as the piston rises further. Initially the cylinder..
