WebJan 1, 2016 · Figure W4a shows a tensiometer where water in a porous cup comes to equilibrium with forces exerted by the hanging water column through the cup as indicated by the height of the column h. The potential is –hρg/1020 bars, where h is measured in centimeters, ρ is the density of water, and g is the acceleration of gravity. WebOct 28, 2013 · The hanging-water column method and the evaporation method provided comparable retention data in the wet to moderate moisture range. The dew point method provided corresponding results over the dry range, while retention data obtained from the pressure plate method sometimes had a tendency to over-estimate water contents. …

WebA soil column is connected to a hanging water column apparatus and allowed to reach equilibrium (qw = 0) - see figure below. The soil surface is loosely covered with plastic so there is no evaporation. Calculate the matric potential and effective radius of water-filled pores at the top of the soil sample. hm = ? 10 cm niter membrane with ...
