The pressure drop through an elbow of 150 mm diameter is to be determined by test on a model. The flow through the elbow is water at 20^oC. The flow velocity is 5 m/s. The model is to be tested with water at 20^oC and the velocity is limited to 10 m/s. Determine the dimeter of the model. If the pressure drop in the model was measured as 15 kpa. Determine the pressure drop in the prototype.
