Before calculating this flux integral, let’s discuss what the value of the integral should be. Based on Figure 6.90, we see that if we place this cube in the fluid (as long as the cube doesn’t encompass the origin), then the rate of fluid entering the cube is the same as the rate of fluid exiting the cube. portable projector for outdoor useWebPart of Matthew Mazowita @abstractmatt, talk at Intersections KW Meetup http://www.meetup.com/Intersections-KW/events/220106808/, Feb. 10, 2015, in Waterloo,... portable projector for iphone 6WebNov 20, 2014 · This talk was given at a local TEDx event, produced independently of the TED Conferences.
