Standard Units Surface Energy: N / m Surface Tension: J/m 2 Volume flow rate: m 3 /s Mass flow rate: kg/s Quantify the Pressure Soap bubble = Laplace’s Law Bottom of lake = Pascal’s law Volume flow rate and the mass flow rate are proportional to each other Laplace’s Law (true) The surfactant must coat particularly areas with a small radius of curvature Fish can float because their density is equal to water. Expression of Conservations Bernoulli = total energy E.o.C = mass Speed of incompressible fluid and cross sectional in a pipe are proportional. Viscosity coefficient: [ Pa * s ] In an experiment with air pressure surrounding the bubble, if pressure increases, radius decreases proportionally In an experiment with air pressure surrounding the bubble, if pressure increases, radius decreases proportionally SI unit for density Kg / m 3 If a negative value for an absolute

Unformatted text preview: pressure is given, then pressure = wrong or a gauge pressure. Which of the following p can be – ve? Pulmonary, alveolar,, or none of these. Speed of fluid to pressure use Bernoulli’s law Volume flow rate to speed = NONE Calculate mass flow rate from cross sectional * fluid speed (in equation of continuity?) = Density Poiseuille’s law- applies as derived only to laminar, incompressible, Newtonian fluiods. - can be used together with E.o.C for the same system. Expression of Conservations Bernoulli = total energy E.o.C = mass Speed and cross sectional in a pipe are proportional. Viscosity coefficient: [ Pa * s ] p = p atm + pgd can be used when When the fluid is \$ a) incompressible b) The fluid is stationary c) Atm above the fluid surface = 0 d) Flud is in mechanical equilibrium...
