‘Head’ and ‘pressure’ in pumps | Water Tech Online

This constant converts a foot of head of water into pressure: Head in feet of water divided by 2.31 equals pressure in psi, and pressure in psi times 2.31 equals head in feet. If the liquid is not water (examples: paint, chocolate syrup or gasoline), the liquid’s specific gravity must be factored into the formula.

Vertical stress in the ground

Stress in the ground Total stress Pore pressure Effective stress Calculating vertical stress in the ground When a load is applied to soil, it is carried by the water in the pores as well as the solid grains. The increase in pressure within the porewater causes drainage (flow out of the soil), and the load is transferred to the solid grains.
