You can imagine my glee when my good friend Andrew asked me a great fluids problem this weekend: He just built a new beer tap system converted from an old chest freezer.  He wants to have nice head on his beer, so he doesn't want it coming out of the tap to quickly.  He was also unsure about the pressure to keep...Read More

Theoretical Fluid Mechanics: Venturi Meter

Posted on by mrsoltys
A Venturi Meter is a device that allows flow rates through pipes to be calculated by measuring the difference in pressure created by a contraction in a pipe.  When the flow goes through the contraction it must speed up, and so the pressure must drop.  By measuring the two pressures, engineers can directly calculate the velocity of the fluid.  Knowing the pipe...Read More
