WebFeb 20, 2024 · The total pressure, or absolute pressure, is thus the sum of gauge pressure and atmospheric pressure: (11.6.1) P a b s = P g + P a t m. where P a b s is absolute pressure, P g is gauge pressure, and P a t m is atmospheric pressure. For example, if your tire gauge reads 34 psi (pounds per square inch), then the absolute pressure is 34 psi plus … WebQ.2: The psia pressure instrument gives the reading as 36.8 psi. If the atmospheric pressure is 16 psi, then calculate the corresponding gauge pressure. Solution: Given values are: Atmospheric pressure \(P_atm = 16 psi\) Absolute pressure \(P_abs = 36.8 psi\) The Gauge pressure is \(P_gauge = 36.8 psi – 16 psi\) = 20.8 psi. high rdw cv% https://primechaletsolutions.com
