WebThe Gradient = 3 3 = 1. So the Gradient is equal to 1. The Gradient = 4 2 = 2. The line is steeper, and so the Gradient is larger. The Gradient = 3 5 = 0.6. The line is less steep, … Webflow net. The upward gradient is computed in the area marked with an X. The total head loss (H) between the last two equipotential lines is 0.62 m. The distance between the two equipotential lines on the downstream end in the X area is 3.3 m. The exit gradient is then computed as 0.62 m divided by 3.3 m, making the upward gradient equal to 0.19.
