Question

releationship between density and pressure​

Answer 1

Density is directly proportional to pressure and indirectly proportional to temperature. As pressure increases, with temperature constant, density increases. Conversely when temperature increases, with pressure constant, density decreases

Answer:

Explanation:

Pressure and Density

The pressure and density relationship for ideal gases and fluids is mathematically written as-

Formula Terms SI units

For ideal gas P=ρRT P is the pressure of the ideal gas pascal or Pa

R is the universal gas constant R=8.31 J/mole/K0

T is the temperature of the ideal gas Kelvin or K0

ρ is the density of the ideal gas. Kg/m3

For fluids P=ρVgAgc P is the pressure of the fluid pascal or Pa or bar

ρ is the density of the fluid lbm/ft3

V is the volume ft3

A is the area ft2

m is the mass lbm

g is the acceleration due to gravity ft/sec2

gc is the gravity constant 32.17lbm-ft/lbf-sec2
