For the PFD calculation the final valve is dominant for the result. The diagnostic coverage of a final valve could be between 75 % and > 90 % depending on the type of valve. The failure rate, safe failure fraction resp. diagnostic coverage of the final valv e and the automatic test time interval have to be used for the PFD calculation. Depending on this calculation and the required

6. Bearing Load Calculation 6.1 Loads acting on shafts To compute bearing loads, the forces which act on the shaft being supported by the bearing must be determined. These forces include the inherent dead weight of the rotating body (the weight of the shafts and components themselves), loads generated by the working forces of the machine, and loads arising from transmitted power. It is

ball. When backspin is placed on a golf ball it will allow the ball to gain loft and have a longer ight. When the ball spins it directs air upwards in front and downward behind it, creating a pressure di erence. The pressure di erence pushes the ball upward allowing the ball to stay in ight for greater time, this is called the Magnus Force.
