Whether for a new design or further development of existing designs you can choose from a variety of methods for bolt calculation in accordance with VDI 2230 within MDESIGN bolt. Simple design calculation allows you by entering the axial force and the lateral force where applicable to determine the bolt diameter, as well as the minimum ...
· Convert result into tons of chiller capacity. Divide Q (BTUs per hour) by 12,000 (the number of BTUs in one ton of cooling capacity). This yields the chiller capacity required to handle the process heat load in tons per hour: Example: 240,000/12,000= 20 tons/hr.
Example Dry vs. Lubried Bolt. The proof load for a M30 metric bolt grad is 337000 N. The torque required to achieve this force with a dry bolt is calculated to 2022 Nm. By failure the bolt is lubried and tightened with the same torque 2022 Nm. The force acting in the lubried bolt can be calculated as
