Approximate weight of a butt welding elbow can be calculated based on its its radius, wall thickness and angle. Please note that actual weight of a elbow from a particular manufacturer may vary depending on manufacturing process. Dimensional standards like ASME B16.9 do not provide weights of butt welding fittings. BW Elbow Weight.

A Wake Frequency Calculation is used to determine or prove the required dimensions and suitability of a Thermowell based on the process conditions. The fluid will form a wake, known as a "Von Karman Trail". The wake has a specific frequency, which is a function of the diameter of the thermowell and the fluid velocity.

Improper valve sizing can be both expensive and inconvenient. A valve that is too small will not pass the required flow, and the process will be starved. An oversized valve will be more expensive, and it may lead to instability and other problems. The days of selecting a valve based upon the size of the pipeline are gone.

Use these design tools to size, choose materials and determine vessel properties such as weight and volume. Useful for creating preliminary designs that meet the general rules and guidelines of ASME VIII Division 1. These can only be used for interior pressure calculations. For simplicity, not all aspects of the VIII-1 code are included -

the set pressure. Pop-acting relief valves do not immediately open completely (to lift). Sufficient overpressure is necessary to achieve full lift. ASME-certified relief valves are required to reach full rated capacity at 10% or less over-pressure. Relief valves are code-certified by the National Board of Boiler and Pressure Vessel Inspectors.
