How do you calculate flow rate using pressure and pipe diameter?
In the Poiseuille equation (p1 – p2) = Δp is the pressure difference between the ends of the pipe (pressure drop), μ is the dynamic viscosity of the fluid, L and R are the length and radius of the pipe segment in question, and π is the constant Pi ≈ 3.14159 to the fifth significant digit.
