When the power is not an integer, you must use this technique of multiplying the percentage uncertainty in a quantity by the power to which it is raised. If the power is negative, discard the negative sign for uncertainty calculations only.

If uncertainties (dX, dY) are provided for the input quantities (X,Y), the program will perform the operation or function to calculate the answer (Z) and will also calculate the uncertainty in the answer (dZ). The program will assume the value has no uncertainty if an uncertainty is not provided.;

The uncertainty of roughness measurements and calibration is usually rather high. This paper gives some methods to estimate the uncertainty properly and proposes a dynamic calibration device and a special reference specimen to enable more accurate roughness measurements.

The uncertainty associated with water fraction measurement is a fundamental consideration of total crude oil measurement and assessing the quality aspects of production. ... A set of ”typical” values for fluid properties and pipe diameter has been chosen as a basis for the calculations, see Table 5.2.
