optimal section

The design concept of the APP comes from the fact that before designing the canal excavation, the engineer needs to calculate the most economical excavation cost and the best cross-sectional area according to the water flow speed and the excavable environment.

With the APP, the excavation depth, the digging width, the hydraulic radius, and the cross-sectional area of ​​the final water can be obtained. Especially suitable for the construction of large canals. Save on mining costs and laying costs. Make the most of it.

When width and depth are limited, you can manually adjust η: the best aspect ratio for the best solution.

Instructions:
1. Register and log in to the app.
2. Enter the basic parameters of the calculation. Such as: Q (flow rate), n (roughness factor), i (cosine value of the bottom slope), etc.
3. Click "Calculate" to get the calculation result.

The product is still in its infancy and more computing content will be improved in the future.
