Fanno Line Flow Calculator

A flow that considers frictional force and is adiabatic is called as fanno flow. This is an online calculator used to find the fanno line flow relation with heat capacity ratio, mach and initial mach number.

Formula:

(s - s_i) / c_p = ln[ (M / M_i)^((γ-1)/γ) * ((1 + ((γ - 1) / 2) * M_i²) / (1 + ((γ - 1) / 2) * M²))^{((γ+1)/(2*γ))}] Where, (s - s_i) / c_p = Fanno Line Flow Condition with Entropy s = Subsonic Flow s_i = Initial Subsonic Flow c_p = Constant Pressure M = Mach Number M_i = Initial Mach Number γ = Heat Capacity Ratio
