Go back through all the calculation posts. As it dragged on, I used a discharge coefficient corrected for a rectangle. The flow came out less than the round orifice. And modeled the flow going through two separate and equal paths, each being 0.75" x 0.020".The calculation was based on using a round orifice. A very high aspect ratio slot would have a much smaller hydraulic diameter, which would affect the results.
Yep, a classic engineer joke.Yes I have heard that joke before. Being an engineer, I have used that joke or similar to it a number of times. The way I have heard it told and that I have told it is with men and women standing on opposite sides of a dance floor and told to advance half the distance between them each time the music stopped. The mathematicians, or physicists in this case, threw up their arms and left knowing that they would never get there. But the engineers stayed knowing that they would get close enough for a practical application.
