Head Loss: What It Is and How to Calculate It - EngineeringClicks

WebTo calculate flow rate from pressure the formula is expressed as such: 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 ... WebThis friction reduces the amount of total head that the pump can produce. In fact, as the flow increases, friction increases and the total head continues to decrease. The amount of head that is lost due to friction is called “friction head” or …
