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.
the total surface area of a prism or pyramid is the combined area of its lateral faces and its base s similarly the total surface area of a cylinder or cone is the combined area of its lateral surface and its base s the total surface area of a solid can also be thought of as the area of the solid s net examples given a bedroom in the shape of a rectangular prism the total surface area is the area of the four walls plus the area of the ceiling and the floor given a cylindrical soup can the total surface area is the area of the can s label plus the combined area of the top and bottom of the can
