A stream is in equilibrium with atmospheric oxygen upstream of a waste outfall. The waste outfall creates a BODo of 20 mg/L in the stream. The k(BOD) is 0.4 /day and the k(o2) is 1.4 / day. The stream temperature is 15 degrees Celsius. How far downstream, in terms of travel time, is the maximum DO sag. What is the minimum DO in the river?
Describe the use of productivity models for estimating land productivity. Provide details about various attributes that can be used and how the model is developed . Examples can be used to demonstrate model workability.
At what temperature does the liquid solidify? What is the composition of this last remaining liquid phase?
Assuming Stokes behavior, calculate the terminal settling velocity in standard air for the following particles: (a). diameter = 10 micrometers, specific gravity =1.2; and (b) diameter = 4 micrometers, specific gravity = 2.0.
The plant currently has one CMFR for removal of chromium. How many more identical reactors does the sony music company require to meet the regulatory requirements for chromium discharge of 0.01 mg/L into the Pitman Sewer?
At an axial load of 23 kN, a 40-mm-wide by 10-mm-thick polyimide polymer bar elongates 2.7 mm while the bar width contracts 0.17 mm. The bar is 240 mm long. At the 23-kN load, the stress in the polymer bar is less than its proportional limit.
Design a series of closely spaced parallel box beams that will support an asphalt road surface over a 10 foot wide, 40 foot long span. The hollow box beams are made of concurred and imbedded No. 8 steel rods (1 inch dia.).
The Earth's surface creates a boundary layer in the atmosphere. The velocity profile near the surface can be expressed as a power law, u = a * y n, where the constants a and n depend on the roughness of the surface.
At a given instant, the position of a plane at A and a train at B are measured relative to a radar antenna at O. Determine the distance d between A and B at this instant.
A 3000-lb car is traveling on a paved road with Cd (coefficient of drag) = 0.35, Af (frontal area of the vehicle) = 21ft^2, and p(air density)=0.002378 slugs/ft^3. Its engine is running at 3000rpm and is producing 250ft-lb of torque.
Office workers complain that the noise level in their office Area 1 is greater than that in the company's other office Area 2. Six measurements are made on different days in each area, with the following results
The height (in meters) of a projectile shot vertically upward from a point 2 m above ground level with an initial velocity of 24.5 m/s is h2+24.5t-4.9t^2 after t seconds. a) When does the projectile reach its maximum height? b) What is the maximum..
The condenser in a refrigerator receives R-134a at 700 kPa and 50C, and it exits as saturated liquid at 25 C, The flow rate is 0.1 kg/s,and the condenser has air in at an ambient temperature of 15 C and leaving at 35 C. Find the minimum flow rate ..
