## Homework Statement

A steel pipeline carrying gas has an internal diameter of

**120 cm**and an external diameter of

**125 cm**. It is laid across the bed of a river, completely immersed in water and is anchored at intervals of

**3 m**along its length.

- Calculate the buoyancy force per meter run.
- Upward force on each anchorage.

Density of steel =

**7900 kg/m**.

2. Equations used

2. Equations used

Buoyancy Force = Weight of the displaced fluid volume

## The Attempt at a Solution

I calculated that the buoyancy per unit length is (approximately),

**1.204 x 10**

^{4}N/mBut I don't see a way to find the answer to the second question. Can someone lead me in the right direction or show me how it's done?
