}
该方法用于计算管件的压降。
参数列表:
返回值:管件压降计算结果,以字典形式返回。字典的键为"Pressure Drop",值为压降值(单位为英寸水柱,inch.wg)。
该方法用于计算附件的压降。
参数列表:
返回值:附件压降计算结果,以字典形式返回。字典的键为"Pressure Drop",值为压降值(单位为英寸水柱,inch.wg)。
以下是一个使用CalculateFittingPressureDrop方法进行计算的示例:
IDuctFittingAndAccessoryPressureDropServer server = new DuctFittingAndAccessoryPressureDropServer();
DuctFitting fitting = // 获取管件对象
double flowrate = 1000; // CFM
double ductPressure = 2; // inch.wg
double roughness = 0.0005; // inch
double temperature = 68; // F
double density = 0.075; // lb/ft³
double viscosity = 0.0000184; // in²/s
double velocityPressure = 0.33; // inch.wg
bool isSupplyAir = true;
bool isSizing = true;
bool isThreeLevelCalculation = false;
Dictionary<string, double> result = server.CalculateFittingPressureDrop(
fitting,
flowrate,
ductPressure,
roughness,
temperature,
density,
viscosity,
velocityPressure,
isSupplyAir,
isSizing,
isThreeLevelCalculation);
double pressureDrop = result["Pressure Drop"]; // inch.wg
