Fluid friction coefficients as well as all other friction coeffs can't be derived or calculated and are empirical in nature so a guess would be a start but would have to be validated. Since we are dealing with a fluid event, there are going to be forces tangent to the wad surface as well as perpendicular. What would the coeff. of friction be for teflon on teflon and would the event realize peak pressure during the teflon-teflon friction?

Kind Regards,
