SUMMARY
The relationship between valve opening and flowrate for butterfly and ball valves is not directly proportional. As flowrate increases, it initially rises quickly but then levels off, resembling a sideways parabola. To accurately compute flowrate, one must apply Bernoulli's equation, incorporating the percentage opening of the valve into the friction loss term. Additionally, obtaining the flow coefficient (Kf) values for both valve types is essential for precise calculations.
