Droplet motion without energy supply
WebDec 11, 2024 · This generates backspin. The ball is moving fast in a forward direction but also slightly in a backward motion. This is what backspin is. Backspin is most useful for the transition between a long shot to the green. Without backspin, the ball will likely roll on for longer than you would want it to. Using backspin slows the ball down after it ... WebThe DC/AC ratio or inverter load ratio is calculated by dividing the array capacity (kW DC) over the inverter capacity (kW AC). For example, a 150-kW solar array with an 125-kW inverter will have a DC/AC ratio of 1.2. On the other hand, a 150-kW array with a 100-kW inverter has a ratio of 1.5. 14 Jun 2024.
