When Patm is pushing harder than  Pgas

$\overline{){{\mathbf{P}}}_{\mathbf{g}\mathbf{a}\mathbf{s}}{\mathbf{=}}{{\mathbf{P}}}_{\mathbf{a}\mathbf{t}\mathbf{m}}{\mathbf{-}}{\mathbf{h}}}$

$\overline{){{\mathbf{P}}}_{\mathbf{g}\mathbf{a}\mathbf{s}}{\mathbf{=}}{{\mathbf{P}}}_{\mathbf{a}\mathbf{t}\mathbf{m}}{\mathbf{-}}{\mathbf{h}}}$

Given:

Patm = 765.2 mmHg
h = 1.30 cm

Convert h first from cm to mm:
