WebUnder control conditions a nominal value for the peritubular capillary pressure is 13 mm Hg. The pressure can also be measured in the termination of the efferent arterioles just as they divide into a cluster of peritubular capillaries, and this pressure is demonstrably higher. WebAnother one: Water is flowing downward through a saturated soil at a flux of 100 cm h-1 (flux is volume per unit cross section area per time). The pressure potential on in the inflow surface is 10 cm and the inflow surface is 20 cm above the outflow surface, which is open to the atmosphere (pressure = 0).
