fluid flow in porous media (petroleum reservoir) Q) Calculate the (order of magnitude of) surface tension of Octane at 293 K. Imagine: 1. The intermolecular interactions for Octane is computed using relation U=KT, where K is Boltzmann constant (1.380610-23J/K). 2. The volume of a single molecule is computed like a cube. 3. Density and molecular weight of Octane are 703 kg/m3 and 0.114 kg/mol. The experimental number is 22 mJ/m^2
