surface tension of water

1. A uniform film of oil 0.13 mm thick separates two discs, each of 200 mm diameter, mounted co-axially. Ignoring edge effects, calculate the torque necessary to rotate one disc relative to the other at a speed of 44 rad ·s−1 (7 rev/s) if the oil has a dynamic viscosity of 0.14 Pa ·s

2. By how much does the pressure in a cylindrical jet of water 4 mm in diameter exceed the pressure of the surrounding atmosphere if the surface tension of water is 0.073 N · m−1?

3. What is the approximate capillary rise of water in contact with air (surface tension 0.073 N · m−1) in a clean glass tube 5 mm in diameter?
