1) One way to study the surface tension effects in a liquid/solid system is to dip a pair of parallel plates into the container of the liquid. How far up in a pair of parallel glass plates, 0.3 mm apart, would water at 40oC be drawn up?

2) A 5 kg block is supported on a thin film of an unknown liquid 0.2 mm thick on an incline of 10o. Determine the viscosity of the liquid if the terminal velocity is 5.678 m/s. Assume the velocity distribution in the gap is linear, and the area of the block in contact with the oil is 0.25 m2. What is the possible identity of the liquid if the temperature is 20°C?
