Abstract
application/pdf
Peek and McLean's differential equation for the dynamical measurement of the wettability of pulverized materials, which has been used elsewhere, is modified slightly by rewriting the apparent mean pore-diameter of the porous media with their specific internal surface and porosity and by correcting the pressure gradient term of the equation of motion describing the rising of a liquid by capillary action. The validity of the corrected term in the above equation has been experimentally verified. Thus, it may be possible to calculate the value of wetting tension, γ cos θ, from the measurement of the penetrating speed by the modified equation without unwarranted assumptions hitherto introduced. That is to say, the calculation of the value of δ from the measurement with the liquid of known wetting tension against the solid.
