The A tannery asked for assistance in prep for NPDES permits to discharge wastewater into X river.
Water quality criterion for X river is 5.00 mg/L of DO.
What is critical DO and where (at what distance) downstream does it occur?
Data is provided below. Flow data pertain to the 7-year, 10-day low flow at the tannery.
Please show calculations and steps in how to set up sag curve with given data.

The suspended load exerts a force F = 600 lb at A and bar OA weighs 200 lb. Assume that the bar's weight acts at its midpoint. Determine the tensions in the cables and the reactions at the ball and socket support O.
an average vehicle puts out nearly 20 lbm of carbon dioxide into the atmosphere for every gallon of gasoline it burns, thus one thing we can do to reduce global warming is to buy a vehicle with higher fuel economy.
The member is supported by a pin at A aand a cable BC. If the load at AD is 300 lb, determine the x,y,z components of reaction at the pin A and the tension in cable b c
The maximum wind pressure on the traffic sign is 200 kg/m2. The maximum allowable shear stress is 350 kg/cm2. Design the traffic pole (only vertical element) against torsion knowing that angle of twist at the base
The grains of wood in the board make an angle of 20 degrees with the horizontal as shown. Determine the normal and shear stresses that act perpendicular and parallel to the grains if the board is subjected to an axial load of 250 N.(Dimensions l=3..
A stream with a flow of 22 mgd contains 180 mg/L of sodium cyanide in the form of NaCN. Chlorine can be added to destroy the NaCN waste according to the reaction shown below. Find the theoretical minimum amount of chlorine required (in lb/day).
Three-point bending test was performed on an aluminum oxide specimen having a circular cross section of radius 5.5 mm; the specimen fractured at a load of 850 N when the distance between the support points was 50 mm.
An engineering student is driving on a level roadway and sees a construction sign 600ft ahead in the middle of the roadway. The students strikes the sign at a speed of 35mi/h. If the student was travelling at 55mi/h
Given the following info., calculate the unit wet weight of asoilmassin pcf and the submerge unit weightin pcf porosity, n=45%
the average values of the test results at four different test temperatires were found to be 10ft.lb -(-50 F) 15 ft.lb- 0F 40 ft.lb- 40F 60 ft.lb-100 F the bridge will be located ina region where specifications require minimum of 25 ft.
calculate the X, Y and Z coordinates of point B for radial readings taken to B from occupied station A, if the backsight azimuth at A is 25°32'48", the elevation of A = 610.098 m, and hi = 1.45 m.
If a cylinder of A-36 steel 1 foot long with a diameter of 1 inch is wedged tightly between two immovable isothermal walls and the cylinder is heated from RTt to 300 c what will happen?describe, do not use an equation
