Hydrostatic pressure (oilfield form)

\n P(psi) = 0.052 × MW(ppg) × TVD(ft)\n

At 10,000 ft with {DEFAULT_PPG} ppg → ~4446 psi.

\n\n

Instructor prompts

Ask trainees to predict the increase for an extra 1,000 ft at {DEFAULT_PPG} ppg (≈ 444 psi).
Discuss how increasing MW (e.g., 8.55 → 10.0 ppg) changes the slope.
Relate display to BHP management: choke vs MW vs TVD.

This visualization is an analogy. Actual subsea/wellbore environments include temperature, compressibility, salinity, and dynamic effects not modeled here.
