Transcript of "Modelling Workshop Fluid Mechanics 2: Problem"

  1. 1. P-W-F-2: "What the hell are you doing?" or "ooh, it is OK." Schlenkerla is a historical brewpub in Bamberg, Bavaria, Germany. It is most renowned for its Aecht Schlenkerla Rauchbier. On the top of the beer barrel, this is a vent, it should be open during the filling process. But in the evening, the vent is sealed and CO2 is pumped in to maintain 2 bar (absolute) pressure. In the past, you designed a 9/16 inch hose for the waiter to fill 1 liter glass within a short time from the drum. One day, the waiter forget to open vent, could you predict what kinds of trouble he is creating (how much beer runs out in the average human reaction time). How can you prevent that? Thedimensions of a barrel Height = 94,80 cm We assume a cylinrical shape and the inside diameter = 60 cm Iron hoops number = 4 Volume 225 liters The density of Schlenkerla Rauchbier is 1.060 g/cm3 The height of the hose is 7 cm from the bottom Assumptions
  2. 2. We assume CO2 + Air in the drum are not dissolved by the beer and the beer don’t release extra CO2 +air in the process. Neglect the resistance of the tubes, consider the resistance of the orifice
