The decrease in the fluid velocity during the initial length of the plate is in accordance with the natural law of absorption. When the void space is fully saturated, due to the presence of the gravitational force and partly due to the inclination of the plate the fluid velocity increases at a rapid rate only in the later part of the plate.</p> <p>&nbsp;</p> https://ultraphysicalsciences.org/paper/1173/ Second order fluid porous boundary visco elasticity of the fluid.
