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 cross section has the same size and shape as the base, as can be seen in the following diagrams. The surface area of a solid is the total area of all its external faces. To calculate the surface area of a prism we need to: Step 1: Determine the shape of each face. Step 2: Calculate the area of each face. Step 3: Add up all the areas to get the total surface area. We can also use the formula. Surface area of prism = 2 Ã area of base + perimeter of base Ã height. Worksheet to calculate the surface area and volume of a rectangular prism. Example: Calculate the surface area of the following prism. Solution: There are 2 triangles with the base = 4 cm and height = 3 cm.
