How is e value calculated in pharmacy?
E= [58.5 x i] / [MW x 1.8] Good, then understand each value. It’s really not too difficult because there is only two variables that changes and it is the “i” and the molecular weight (MW).
How do you calculate WW?
If you were making 100 g of your product and add 50 ml of the oil during manufacture, this will be 50 x 0.9 g/ml = 45 g. Therefore, in 100g of your product’s solution, 45 g of this will be your oil, meaning that it has a %w/w of 45.000.
How is flow rate calculated in pharmacy?
To calculate the drops per minute, the drop factor is needed. The formula for calculating the IV flow rate (drip rate) is total volume (in mL) divided by time (in min), multiplied by the drop factor (in gtts/mL), which equals the IV flow rate in gtts/min.
How do I calculate WW?
%w/w concentrations – example: If you were making 100 g of your product and add 50 ml of the oil during manufacture, this will be 50 x 0.9 g/ml = 45 g. Therefore, in 100g of your product’s solution, 45 g of this will be your oil, meaning that it has a %w/w of 45.000.
What is e value formula?
Finally, the E-value is calculated as E=mn2-S, where m is the effective length of the query, and n is the effective length (total number of bases) of the database.
What measurement system is used for pharmaceuticals?
The metric system is by far the most commonly used system of measurement through- out the world, as well as throughout science and medicine. The metric system is the legal standard of measurement for pharmacy and medicine in the United States.
What is W W and W V?
% volume per volume (v/v), % weight per volume (w/v) and % weight per weight (w/w) Introduction. These variations on percentage concentration are used in chemistry and biology when making up solutions and have the following meanings.
What is the analysis process of load bearing structure?
Analysis Process of Load Bearing Structure: The load bearing structure is determined by the analysis process as given below; Initially, the whole structure is analyzed and the function of each structural element is thus determined. Then the forces in the individual structural elements are determined.
How do you Compute bearing loads?
To compute bearing loads, the forces which act on the shaft being supported by the bearing must be determined. Loads which act on the shaft and its related parts include dead load of the rotator, load produced when the machine performs work, and load produced by transmission of dynamic force.
What is the dynamic equivalent radial load of a bearing?
For radial bearings, this load is expressed as pure radial load and is called the dynamic equivalent radial load. For thrust bearings, it is expressed as pure axial load, and is called the dynamic equivalent axial load. (1) Dynamic equivalent radial load The dynamic equivalent radial load is expressed by formula (4.17). P r＝XF r＋YF
What are the advantages of load bearing structure?
The load bearing structure provides high strength and durability to the building. These structures do not require time-consuming preparation. This structure is suitable for up to three stories Buildings. After the construction, it is not possible to alter the position of walls.
