摘要
在讨论水舌挑距计算式的基础上,全面分析了影响挑距计算的各种因素包括反弧鼻坎挑角、水舌出射角、流速系数、反弧水流坦化,反弧半径及空气阻力等,并给出了各种参数的选择方法。
In this paper, we analyze the formula for calculating horizontal length of jet flow and the factors, which effect horizontal length of jet flow, including the bucket's angle, outflow angle of jet flow on the bucket, coefficient of speed, flattening of the surface streamline, bucket's radius, and resistance force of air. We also suggest the method for calculating the various factors.
