摘要
针对经验公式在实际应用中的不足 ,利用积分方法 ,在经验公式的基础上推导出流量损失与毛流量之间的关系式。结合目前灌区的实际情况 ,根据所推导的新公式 ,进一步分析研究了配水渠道流量损失的求算方法。
Aiming at the shortcoming of empiric formula in actual application, by using of integral method a new formula for the relationship between water losses and gross discharge is established. In consideration of actual situation of irrigation district, according to new formula a calculation method of water losses in distribution canals is deduced.
