Wall Stress correct answers Wall Stress = Intraventricular Pressure x Radius / Wall Thickness Law of LaPlace in cylinder equation correct answers T = Pr T = wall tension P = pressure of liquid within cylinder r = radius Reynold's number equation Laminar flow vs turbulent flow correct answers Reynold's number = (Density x diameter x velocity) / viscosity Laminar flow = 2000 Turbulent flow = 4000 Ideal Gas Law correct answers PV=nRT P= Pressure V= volume n= number of moles, R= constant = 62.4 Torr or 62.4 mmHg — needs to be equal to pressure unit T = Temp Kelvin = 273 + degrees C Boyles charles and guy lusacs mneumonic correct answers Could These Girls Possibly Be Virgins Fick's Law of Diffusion correct answers Diffusion rate = (P1-P2) · (Area) · (Solubility) ______________________________________________________________ (membrane thickness) · (square root of MW) Poiseuille's Law correct answers Q = flow p = pressure (change in pressure / pressure gradient) r = radius n = viscosity l = length of tubing Ohm's Law correct answers Ohms law says that current passing through a conductor is directly proportional to the voltage and inversely proportional to the resistance. We can adapt Ohm's law to understand fluid flow
