The capillary pressure of a soft white paper is measured with an experiment and the results are given in the table given at right :

a$)$ Draw the graph using ruler neatly. $(5$P$)$

b$)$ Calculate AP $($hydrolic pressure$)$ using the highest height of water penetrated in the paper, and from $R_C=\frac{2{}_{iv}cos}{P},cos9$~~$1,{}_{iV}=0\mathrm{.}072\frac{N}{m}$ at $T=25C.$ calculate average pore diameter that the soft paper possess. $(5$ P$)$

c$)$ From data, calculate average penetration velocity of water, and calculate the viscosity of water at

$T=25C$ using $=\frac{2Y_{Lv}cos{R}_C}{gra{d}_{4}4H},V_{?}=$ Average velocity

$H=$ Max. Height $(5P)$
