摘要：

Blasins equation for friction coefficient is used to determine energy drop between outlets along a drip irrigation line. The energy gradient line is a curve of exponential type which can be determined by calculating energy drop of all sections along the line. A simple way of estimating energy gradient line with only about 1% of error can be done by dividing the line into three or four segments and using the average discharge for each segment to calculate energy drops along the line.
