Drag losses in oil jet lubrication

To calculate drag losses for the oil jet lubrication method, use the oil bath model, with the oil level H at half the diameter of the lowest rolling element. The obtained value for Mdrag should be multiplied by a factor of two. Certainly, this approximation can vary depending on the rate and direction of oil. However, if the oil level H is known when oil is flowing and the bearing is at a stand-still, this value can be used directly in the drag loss calculation to obtain a more accurate estimate.
