Pressure, psi = 0.052 x Mud Weight (ppg) x TVD (ft)
I got the question asking about how the constant 0.052 is figured out.
What is 0.052?
0.052 is a constant used for converting ppg-ft into pound per square inch (lb/in2)
Do you know how it comes from? Let's get started
First of all, the unit conversions that you need to know are as follows:
1 gallon = 231 cubic inch (inch3)
1 ft = 12 inch
Convert density from ppg (pound per gallon) to lb per cubic inch
Basic hydrostatic pressure
The constant can be determined by substituting the unit conversion.
The constant is 0.051948 and if we round it up, it will be 0.052.
