V gy Froude number Fr = is important in open channel flow of water, because a. Open channel flow has a pressure that is different everywhere. b. Open channel flow is with a free surface and the flow is driven by gravity. gy represented a wave from bottom to surface. d. Wetted perimeter of water channel P can be a rough surface.

8) Cheater knowing Fluid Dynamics? - Red Sox ace Jon Lester pitched against the St. Louis Cardinals in Game 1 of the 2013 World Series, scattering five hits while striking out eight players over 7.2 scoreless innings en route to an 8-1 Boston win for an early 1-0 series lead. But people noticed that he constantly rubbed the ball against the inside of his glove, maybe with resin or some other gel? Or trying to roughen the ball with a...

An open channel flow in a hydraulic lab is designed to line artificially with corrugated metal. To keep the shape and all other conditions the same, the designer can simply replace the corrugated metal with brass and the flow rate (Q, in mº/s) of the channel will Decrease by 50% b. Increase by 50% Double d. Quadruple a. C.

Open channel flow must have a surface. Because of the free surface, is the driving force in open channel flow. The application of the equation is most effective to estimate the rapid loss of energy when determining the shape of flow profiles for Rapidly varied flow. Flow in open channels is mainly in the regime. Depth of Flow (y or d) – is the vertical distance of the lowest point of a channel section from the surface. In slope is...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
