Question
Note: In the text, all questions use 62.5 pounds/ft as the force per volume density of water.
In metric, we would need Newtons/meter. The mass density per volume of water is 1000 kg/m³.
To convert this into a force density per volume, we multiply by gravity, approximately 9.8 m/s?. The
resulting quantity is the force density per volume in metric: 9800 N/m³.
