The former makes the IP compressor surge line shallower, swinging it away from the shallow working line, thus improving IP compressor surge margin. At a given IP compressor pressure ratio, opening the blow-off valve forces the IP compressor entry corrected flow to increase, to a point where the IP compressor surge margin tends to be better.
In engineering, a factor of safety (FoS) or safety factor (SF) expresses how much stronger a system is than it needs to be for an intended load.Safety factors are often calculated using detailed analysis because comprehensive testing is impractical on many projects, such as bridges and buildings, but the structure's ability to carry a load must be determined to a reasonable accuracy.
Special memorandum account (SMA) [1] is a margin credit account used for calculating US Regulation T requirements on brokerage accounts. In addition to Initial Margin and Maintenance Margin requirements, the SMA ledger is used to lock in unrealized gains that augment the client's buying power. According to Regulation T, Section 220.5: [2]

Randomly varying channel gains such as fading are taken into account by adding some margin depending on the anticipated severity of its effects. The amount of margin required can be reduced by the use of mitigating techniques such as antenna diversity or multiple-input and multiple-output (MIMO). A simple link budget equation looks like this:
The hydraulic calculation procedure is defined in the applicable reference model codes such as that published by the US-based National Fire Protection Association (NFPA), [2] or the EN 12845 standard, Fixed firefighting system – Automatic sprinkler systems – Design, installation and maintenance. [3] Hydraulic calculations indicate that the ...
Using gross margin to calculate selling price Given the cost of an item, one can compute the selling price required to achieve a specific gross margin. For example, if your product costs $100 and the required gross margin is 40%, then Selling price = $ 100 1 − 40 % = $ 100 0.6 = $ 166.67 {\displaystyle {\text{Selling price}}={\frac {\$100}{1 ...
In business, Gross Margin Return on Inventory Investment (GMROII, also GMROI) [1] is a ratio which expresses a seller's return on each unit of currency spent on inventory.It is one way to determine how profitable the seller's inventory is, and describes the relationship between the profit earned from total sales, and the amount invested in the inventory sold.
