💨 Air Density Correction Calculator

Correct fan Static Pressure and Power for non-standard operating conditions.

1. Input Reference Performance (Standard Density)

Reference Static Pressure (P_std)

Reference Power (W_std)

2. Input Actual Operating Conditions

Actual Temperature (T)

Absolute Pressure (P)

Standard Air Density (ρ_std)

Commonly 1.2 kg/m³ or 0.075 lb/ft³

Note on Air Density: This calculation uses the Ideal Gas Law (ρ = P / (R_sT)) assuming dry air (R_s = 287.05 J/(kg·K)). Actual pressure and power are directly proportional to the Density Ratio (DR = ρ_Actual/ρ_Standard).
