What suction (or negative pressure) is required to support a column of liquid 20 m high? Does this exceed the tensile strength of water?

2. Relevant equations

Bulk Modulus = (Change in Pressure/ (Change in Volume/Volume))

Pressure = Force / Area

3. The attempt at a solution

Tensile strength of water = 20 MPa

Pressure = Force / Area

Assume column has a diameter of 1 unit.

The surface area of this column is thus:

Circumference x Height of column + Area of top of column

= 62.83 + 0.79

=63.62 units^{2}
