Kinetic theory — pressure
P = ⅓ρv²_rms
Where: P = power (W) / pressure (Pa), ρ = density (kg/m³) / resistivity, vᵣₘₛ = vᵣₘₛ
Solved example
Given: rho = 7, v_rms = 5
Find: P (power (W) / pressure (Pa))
- Formula: P = ρ·vᵣₘₛ²/3
- Substitute the values: P = 5²·7/3
- Result: P = 58.333333
Answer: P = 58.333333
