This is because at 90\u00c2\u00b0, the water will flow into the canal without any turbulence or splashing. If the angle is less than 90\u00c2\u00b0, the water will flow into the canal at an angle and will create turbulence. If the angle is greater than 90\u00c2\u00b0, the water will flow into the canal at a sharp angle and will create splashing.<\/p>\n<p>Here is a diagram that illustrates the different angles and their effects on the flow of water:<\/p>\n<p>[Diagram of a canal with a head regulator at different angles]<\/p>\n<p>As you can see, the water flows smoothly into the canal when the angle is 90\u00c2\u00b0. However, when the angle is less than 90\u00c2\u00b0, the water flows into the canal at an angle and creates turbulence. When the angle is greater than 90\u00c2\u00b0, the water flows into the canal at a sharp angle and creates splashing.<\/p>\n<p>Therefore, the angle between the head <div
