A fine-bubble aeration basin has a flow of 21.5 mgd, an influent BOD of 180 mg/l, 31 mg/l of mmonia, and effluent of 10 mg/l. During the winter, the wastewater temperature of 14.8 degrees C does not nitrify.
The velocity of the center point of the wheel is constant at 20 ft/sec to the right. For the instant, determine the following: a) The velocity and acceleration of point B (which is attached to the wheel) measured with respect to ground.
Draw the influence line for the support reaction at A and calculate the support reaction at point
The vertical velocity of the box at the time that it hits the surface is v= 5m/s. After impact the camera experiences an acceleration of a = -kx, where k is a constant and x is the compression of the packing material.
