A numerical method to solve the Bernoulli equation is proposed. By using this method, the velocity distribution and pressure distribution in the riser can be analyzed through the whole process of low-pressure casting, and the simulation of the rising process of low pressure casting can be realized. Thus solving the difficult problem of solving the Bernoulli equation by analytical method under the actual production conditions. In order to optimize low-pressure casting pressure process, improve the quality of castings provides a scientific tool.
