factor of safety 3. volume 50 m3. How do I calculate the internal pressure and diameter, which I will need to calculate the shell thickness.The relation between length and diameter is not given.Also, is the data given to me insufficient to design the pressure vessel? Engineering news on Ph...
A simple example will help illustrate the concepts of SIS, SIF, and SIL. Consider the installation of a pressure vessel containing flammable liquid. It is maintained at a design operating pressure by the BPCS. If the process control system fails, the vessel will be subjected to an over-pressu...
How to calculate the landed cost of imported products. Firstly, it’s important to understand all of the different costs, fees and charges involved throughout the purchasing and importing process. Below is a list of information that you will need to know to accurately calculate the landed cost...
In order to measure a ship's top speed, they calculate an average that takes into consideration going with and against the waves in the ocean. The weather plays a major role in how fast a ship could travel, just like how an airplane's top speed can depend on how strong of a tail or...
How to Calculate Cell Density To calculate the cell density in cells/mL, take the average cell count per major square and multiply by 104(remember, the volume of one major square is 0.1 μL, or 0.0001 mL = 1x10-4mL), then multiply that by the dilution factor. ...

A packing list may be required by customs to check compliance and calculate duties. It can also be used by banks for reimbursement under a letter of credit or other payment terms. There are different ways to create a packing list template, depending on the type of shipment and how the good...
be transported is simply one aspect of the problem. The ship’s size is another important component in influencing the pricing. A larger length not only takes up more room, but it’s also typically reflective of weight, which might put additional pressure on the vehicle delivering your vessel...
force to level. A bubbler-type level sensor is shown in Figure 3. This technology is used in vessels that operate under atmospheric pressure. A dip tube having its open end near the vessel open carries a purge gas (typically air, although an inert gas such as dry nitrogen may be used ...
With the increasing weight ofcargo ships, the most cost-effective design strategy to prevent collapse of bridges due to vessel collision may well be to protect the bridge piers from the impact. This is done by building a bridge collision protective system, which is often a concrete or rock st...
