SUMMARY

To convert 20mm of gas to Pascals, one must use the formula P = hρg, where P represents pressure in Pascals (N/m²), h is the height in meters (20mm = 0.02m), ρ is the density of the gas in kg/m³, and g is the acceleration due to gravity (approximately 9.81 m/s²). The density of the specific gas must be known to complete the conversion accurately. This formula applies universally to fluid statics and is essential for calculating pressure in various applications.

PREREQUISITES
  • Understanding of fluid statics principles
  • Familiarity with SI units and conversions
  • Knowledge of gas density measurements
  • Basic grasp of gravitational acceleration (g = 9.81 m/s²)
NEXT STEPS
  • Research how to calculate the density of different gases
  • Learn about fluid statics and pressure calculations
  • Explore the implications of pressure in various engineering applications
  • Study the effects of altitude on gas density and pressure
USEFUL FOR

Students in physics or engineering, professionals in fluid mechanics, and anyone involved in pressure measurement and gas properties will benefit from this discussion.

i know this probably sounds really stupid but how do i convert 20mm of gas into pascals?
thnx

Pa has units of N/m^2 thus you need a little more info to convert 20mm of gas to pascals.
 
p = h \rho g, when you use SI units in the RHS, P is in N/m^2. You need to know the density of the gas. g is the accelaration of gravity.
