1
pressure formula
p = F/A
2
Patm at sealevel
1 atm, 14.7 psi
3
Pabs, Patm, and Pg relationship
Pabs = Pg - Patm
4
density formula
ρ= m/V
5
specific weight
γ= ρg
6
SGliq and SGgas formulas
SGliq = (ρliq / ρwater) = (γliq /γwater)
SGgas = (ρgas / ρair) = (γgas /γair)
SGgas = (ρgas / ρair) = (γgas /γair)
7
ρwater and ρair
ρwater @ 4'c = 1000 kg/m^3
ρair =1.205 kg/m^3
ρair =1.205 kg/m^3
8
volumetricand mass flow rate formulas
9
mass and mole fractions
10
avg molecular weight formula
11
hydrostatic pressure formula
