The uncertainty analysis report should also include an error equation or model for each measured. quantity. The error equation or model should provide an algebraic expression that defines the. total error in the value of the quantity in terms of all relevant measurement process errors. In the.
There are different methods used to measure surface area and each method can yield different results. Most methods are based on the isothermal adsorption of nitrogen. Either a single point or multipoint method is used to calculate the surface area.he total to determine the method used to determine surface area, Table 1, showed that six of the respondents used a single point surface area of a catalyst can be measured by either a multipoint or single point technique.
In words, the surface area of a rectangular prism is the area of the six rectangles that cover it. But we don't have to figure out all six because we know that the top and bottom are the same, the front and back are the same, and the left and right sides are the same.he surface area is the areas of all the parts needed to cover the can. That's the top, the bottom, and the paper label that wraps around the middle. You can find the area of the top (or the bottom). That's the formula for area of a circle (pi r2).
