गणितीय रुप से,इसे निम्न प्रकार से निरुपित किया जा सकता है:
निरपेक्ष दाब = वायुमंडलीय दाब + गेज दाब
Pabs = Pgauge + Patm
गणना:
दिया गया है:
h = 5 m
Patm = पारे का 0.75 m = ρHg × g × 0.75 = 13600 × 9.81 × 0.75 = 100062 Pa
Pgauge = ρwater × g × h
Pgauge = 1000 × 9.81 × 5 = 49050 Pa
Pabs = Pgauge + Patm
Pabs = 49050 + 100062
Pabs = 149112 Pa = 149112 N/m2 = 0.149 N/mm2 ≃ 0.15 N/mm2
