I have an issue in the model, If you check the T-1 & T-3 inlet it was connected as a top inlet. When I run the simulation for avg daily demand I don't have any issue. However, when I check the properties of the tank the inlet pipe it shows negative flow. Even I tried to adjust the discharge co-efficient factor seems no change in the result. Moreover, I have issues with velocity and pressure in the model. Please check the Model uploaded in the following link.
