Frequently Asked Questions
-
What does pound per cubic yard measure?
-
It measures density by expressing the mass in pounds contained within one cubic yard of volume, often used in construction and engineering.
-
Why convert pound/cubic yard to psi/1000 feet?
-
Converting helps relate material density to hydrostatic pressure gradients, important in drilling, well control, and structural calculations.
-
Are there any assumptions in this conversion?
-
Yes, it assumes uniform density and hydrostatic conditions over the measured vertical depth, which may not always be true in practice.
Key Terminology
-
Pound/cubic yard (lb/yd³)
-
A density unit indicating pounds of mass contained in one cubic yard of volume, commonly applied in construction and engineering contexts.
-
Psi/1000 feet
-
A pressure-gradient unit expressing the change in pounds-force per square inch of pressure for every 1,000 feet of vertical depth, used in petroleum and wellbore engineering.
-
Hydrostatic pressure gradient
-
The rate at which pressure increases with depth due to the weight of a fluid column, often expressed in psi/1000 feet.
