Question

Estimate the theoritical energy required to create the nanoemulsion in water in joules

Answer 1

For the nanoemulsion system described in the above homework, estimate the theoretical energy required to create the nanoemulsion in water in Joules. Surface tension of water is 72.8 mN/m. Surface tension of oil is 21 mN/m and the oil-water interfacial tension is 51 mN/m. Asssume the initial 50cc oil is present as a large spherical oil droplet in water.

"above hw"

50 ml of mineral oil is mixed with a liter of water and is subjected to high shear to create 100 nanometer spherical oil droplets. Calculate the new surface area of droplets in square meters and the number of droplets in the resulting emulsion. Assume the density of mineral oil to be 0.85 gms/cc.
