A single source of BOD causes an oxygen sag curve with a minimum downstream DO equal to 6.0 mg/L. If the BOD of the waste is doubled (without increasing the waste flow rate), what would be the new minimum downstream DO? In both cases assume that the initial oxygen deficit just below the source is zero and the saturated value of DO is 10 mg/L. (Note that when the initial deficit is zero, the deficit at any point is proportional to the initial BOD)
The channel cross section is rectangular in shape,with a bed width of 4 m and Manning n of 0.022. The bed drops by an average of 4.2metres every kilometre. The maximum flow in the channel is equal to 7 m3/s.
compute the allowable load on a column with fixed ends if it is 5.45 meters long and made from an S150 x 18.6(S6 x 12.5) beam. The material is ASTM A36 steel. Use the AISC formula.
A nozzle is designed to linearly accelerate the fluid from V1 to V2 (i.e., V = ax +b, where a and b are constants). Determine the local acceleration, the convective acceleration, and the total acceleration at point 1 and 2 at t = 0.
A rectangular sedimentation basin will have a flow of 1.0 mgd using a 2:1 legth/width ratio, and overflow rate of 0.00077 fps, and a detention time of 3.0 hr. What will the dimensions of the basin be
If friction between the cars and the rails is neglected, what were the magnitude and the direction of the velecity of the cars after the collision?
How to calculate the principle of shoring system in formwork analysis when the secondly floor upper has been poured?
The barrel has an inner diameter of 4ft. Neglect its wall thickness. Assume that only the hoops resist the water pressure. Note: Water develops pressure in the barrel according to Pascal's Law, p=62.4 lb/ft^2, where z is the depth from the surface..
A building frame is made with a 10" square steel box shape that has an area of 15 in^2 and a moment of inertia I =225 in^4. The frame consists of pinned supports at points A and F and an internal pin at point D.
