A 250 cubic meter reaction tank contains a waste water having an ultimate BOD concentration of 755 mg/L. If the BOD reaction rate constant is -0.352/day, how much BOD is remaining after 12.0 days?
The block is released from rest when the spring is unstretched (at x=0). We wish to show that the ensuing motion of the block is simple harmonic. Call the initial configuration of the system that existing just as the block is released from rest.
The storage in a rectangular section irrigation channel is 20,000 m2 at a given time. Determine the storage 1 hour later if the average rates of inflow and outflow during the hour are 23 and 18 m3/s respectively.
The hypothetical velocity distribution in a horizontal, rectangular open channel is V=0.3y (m/s), where V is the velocity at a distance y (m) from the bottom of the channel. If the vertical depth of flow is 2 m and the width of the channel is 4 m,..
The rain¬fall amounts at three adjacent stations A, B, and C were 4.2, 3.7, and 4.9 in., respectively. The average annual precipitation amounts for the gauges are X = 36.5, A = 42.1, B = 37.1, and C = 39.8 inches.
A polystyrene rod consisting of two cylindrical portions AB and BC is restrained at both ends and supports two 6-kip loads as shown. Knowing that E = 0.45 X 106 psi,
Find the angular velocity and angular acceleration needed to keep the prisoner in the beam of the spot light at the moment when the prisoner is 4000 ft away from the spot light.
Two level sections of an east highway (G=0) are to be connected. Currently, the two sections of highway are seperated by a 4000-ft (horizontal distance), 2% grade.
Determine the drag force FD on a golf ball assuming it is a smooth sphere. (Assume the air is at 60 F and standard pressure.) Now determine the drag force on an actual golf ball assuming CD = 0.25. How do the two forces compare
Determine the major and minor principal stresses at failure and the effective stress friction angle (assume c' = 0). Plot the Mohr diagram.
A well water has the following mineral contents in mg/L: Na+=20; K+=35; Ca+2 =15; Mg+2 =10; Sr=0.5; Cl- =40; HCO3- =65; CO3-2=5; SO4-2=15; and NO3=10.
a moist soil has a total unit weight of 110 pcf and a water content of 6 percent. assuming that hte dry unit weight is to remain constant , determine how much water , in gallons per cubic yard, must be added to increase the water content to 12 per..
Just below the point where a continuous discharge of pollution mixes with the river, the BOD is 10.9 mg/L and the DO is 7.6 mg/L. The river and waste mixture has a temperature of 20oC, a deoxygentation constant of 0.2/day
