1. What is the rise of water in a vertical crack formed by two glass plates 20
m apart?

2. Calculate the capillary rise of water in a pair of the glass plates separated by 2 mm if the plates are inclined at 75◦ from the vertical.

3. Water flows from a pipe at 6 m/s. What is the kinetic energy per unit mass of the water? What is the kinetic energy per unit volume of water?
