A system of seven river segments is shown in the schematic diagram. The , and 's ( to 7 ) are the river segments, their corresponding flow rates, and concentrations of a conservative pollutant, respectively. Assume complete mixing at the intersections, no additional water loss or gain in the system and steady state condition. Given : . What is the steady state concentration in , rounded off to two decimal place) of the pollutant in the river segment 7 ? ____
Crown corrosion in a reinforced concrete sewer is caused by:
Assertion [a]: At a manhole, the crown of the outgoing sewer should not be higher than the crown of the incoming sewer. Reason [r]: Transition from a larger diameter incoming sewer to a smaller diameter outgoing sewer at a manhole should not be made. The CORRECT option evaluating the above statements is :
Determine the correctness or otherwise of the following Assertion [A] and the Reason [R] : Assertion :The crown of the outgoing larger diameter sewer is always matched with the crown of incoming smaller diameter Reason : It eliminates backing up of sewage in the incoming smaller diameter sewer.
An existing 300 mm diameter circular sewer is laid at a slope of 1:28 and carries a peak discharge of 1728 /d. Use the partial flow diagram shown in the given figure and assume Manning's n = 0.015 At the peak discharge, the depth of flow and the velocity are, respectively
