Turgor and Cell Expansion: Beyond the Lockhart Equation

The Lockhart–Martinelli parameter () is a dimensionless number used in internal two-phase flow calculations. It expresses the liquid fraction of a flowing fluid. Its main application is in two-phase pressure drop and boiling/condensing heat transfer calculations. It is defined as: where Witrynashowed that Y, and probably m, in the Lockhart equation must have adjusted to sustain the same growth rate at a reduced turgor. After 2 h of stress the medium bathing the root was changed back to 0.1 m M CaCl 2. There was an immediate, steep increase in turgor, and a burst of growth (Fig. 2). After the initial burst, however, growth luthier apprenticeship programs https://clarionanddivine.com
