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.
Surface Area of the Earth. by Jerry Coffey on February 18, 2009. The surface area of the Earth is 510 million square kilometers or 5.1Ã10 8 km 2. The Earth is a water heavy planet, so, if you break its surface area into water and land segments, it would look like this: land 149 million km 2, water 361 million km 2. Letâs look at how the surface area of the Earth compares to the surface area of the other planets in our Solar System and our Moon.
