The BAC is usually expressed as a percent based on weight/volume. This means that the BAC is the grams (g) of alcohol present per 100 mL of blood. For example, a BAC of 0.12% is equivalent to 0.12 g alcohol per 100 mL of blood. At 0.12%, most people are intoxicated! Typically 100 mL is referred to as 1 deciliter or 1 dL. So, 0.12% is also equivalent to 0.12 g/dL. The BAC can be calculated based on how much...

The Equation of Continuity states that the mass flow rate has the same value at every position along a tube that has a single entry and a single exit point for fluid flow. Basically it boils down to the idea that the fluid doesn’t magically disappear or appear. If 2.0 kg of fluid flows past a point in a tube in a time of 1.0 s, then 2.0 kg of fluid flows past another point in that tube in 1.0...

An artificial kidney uses porous hollow fibers to purify blood. Blood containing urea flows through the fibers and urea diffuses out, through the porous fiber wall. Tens of thousands of such fibers were used in an artificial kidney. We would like to determing the fraction of the urea removed as blood flows through one such fiber. The fiber has a radius of R = 100 µm and length L = 10 cm. The flow rate of blood (viscosity 0.03 g/cm/s...
