Fanno Flow Calculator
A process without the transfer of heat (adiabatic) and with friction is called as the fanno flow. This is an online calculator to find the pressure, temperature, density, velocity and stagnation pressure ratios of the fanno flow.

Formula:
T / T* = 1 / [(2 / (γ + 1)) * (1 + ((γ - 1) / 2) * M2)]
Where,
T / T* = Fanno Flow Temperature Ratio
T = Temperature
T* = Temperature with Throat location
M = Mach Number
γ = Heat Capacity Ratio
Formula:
P / P* = (1 / M) * (1 / √((2 / (γ + 1)) * (1 + ((γ - 1) / 2) * M2)))
Where,
P / P* = Fanno Flow Pressure Ratio
P = Pressure
P* = Pressure with Throat location
Formula:
ρ / ρ* = (1 / M) * √((2 / (γ + 1)) * (1 + ((γ - 1) / 2) * M2))
Where,
ρ / ρ* = Fanno Flow Density Ratio
ρ = Density
ρ* = Density with Throat location
Formula:
P0 / P0* = (1 / M) * [(2 / (γ + 1)) * (1 + ((γ - 1) / 2) * M2)]((γ+1) / (2*(γ-1)))
Where,
P0 / P0* = Fanno Flow Stagnation Pressure Ratio
P0 = Stagnation Pressure
P0* = Stagnation Pressure with Throat location
Formula:
V / V* = M / √((2 / (γ + 1)) * (1 + ((γ - 1) / 2) * M2))
Where,
V / V* = Fanno Flow Velocity Ratio
V = Velocity
V* = Velocity with Throat location
