弯管水流流量压差关系公式推导与验证

Derivation and Verification of the Formula of Discharge and Difference Pressure in Elbows

从分析弯曲管道内水流运动规律出发，推导了弯管水流流量压差关系的基本公式，并通过实验实测资料的计算分析，验证了这一基本公式的正确性，取得了规律性的有价值的研究成果．

Proceeding from the analysis of water movement law in elbows pipe, the.fundamental formula of discharge and pressure difference in elbow has been derived in thispaper. By the calculation and analysis of the test data, the validity of the formula has beenproved and the valuable result obtained.
