The uncertainties associated with the measurement of pressure, temperature, mass flow rate and mole fractions affect the heat and mass transfer results discussed in Figure 4.4. Type-A uncertainty, which considers random variation of the measured variable around the sample mean is represented by the standard deviation of the mean and is calculated using Equation (4.1) (Coleman and Steele, 1989). 1N 212 UA NN1Xi X (4.1)  i1  Type-B uncertainty is the systematic error or the manufacturer specified uncertainty for the specific component. Equation (4.2) is used to calculate systematic error in the measurement by sensors. Total uncertainties for all the components are calculated using Equation (4.3) and are listed in Table 4.1 (Coleman and Steele, 1989). N  Y   a X  b   2 ii U 2  i1   (4.2) (4.3) B N2 U2 U 2 U 2 AB Table 4.1.

Engineering Equation Solver (EES) software (Klein, 2016) is employed to calculate uncertainty propagation in the adsorption time.
