Grashof Number Calculator

Grashof Number Equation

$$ Gr = \frac{g \beta \Delta T L^3}{{\nu}^2} $$ where:

Gr = Grashof Number (Dimensionless)

g = Gravitational Acceleration (m/s²)

β = Thermal Expansion Coefficient (K^-1)

Δ T = Temperature Difference (K)

L = Characteristic Length (m)

ν = Kinematic Viscosity (m²/s)
