Method "Values for water fluxes are means ± SD. Matched hemibladders from 5 toads were filled with Ringer fluid and suspended in Ringer fluid containing 20 mU/ml vasopressin at 21°C. After 15 min bladders were fixed with glutaraldehyde, filled with distilled water, and suspended in a hormone-free solution of 232 mM mannitol and 1 mM CaCl2. Water fluxes were measured at 15-min intervals at temperatures indicated in the table and all fluxes were normalized to control values at 21°C. Values for viscosity of water taken from Handbook of Chemistry and Physics (primary source)."
Comments Viscosity is the ratio between the pressure exerted on the surface of a fluid, in the lateral or horizontal direction, to the change in velocity of the fluid as you move down in the fluid. cP=centipoise=0.001Pa×sec
