Frequently Asked Questions
-
What does pound per cubic foot measure?
-
Pound per cubic foot measures mass density by expressing the mass in pounds contained in one cubic foot of volume.
-
Why convert lb/ft³ to psi/1000 feet?
-
Converting to psi/1000 feet allows engineers to understand pressure gradients related to fluid density, useful in petroleum and wellbore engineering.
-
Can this conversion be used for non-vertical depth settings?
-
The conversion is primarily valid for vertical depth and hydrostatic conditions; applying it outside these contexts may reduce accuracy.
Key Terminology
-
Pound per cubic foot [lb/ft³]
-
A unit expressing mass density as pounds of mass contained in one cubic foot of volume within the imperial system.
-
Psi/1000 feet
-
A pressure-gradient unit representing the increase in pressure per 1000 feet of vertical depth, used to relate hydrostatic pressures to fluid density.
-
Hydrostatic pressure gradient
-
The rate of change in pressure within a fluid column due to gravitational forces, typically expressed in psi per 1000 feet for subsurface engineering.
