Hence, The System Curve Does Not Follow The Curves Of Constant Efficiency. Instead, It Intersects Them (see Figure ES-6). The Reduction In Flow Is No Longer Proportional To Speed; A Small Turn Down In Speed Greatly Reduces Flow Rate And Pump Efficiency. A Common Mistake Is To Also Use The Affinity Laws To Calculate Energy Savings In 2th, 2024
