Nu = hD/k ± uNu = 5.00 ± 0.385 (95%)
So, Nusselt number can be determined within about 8% in this range of values.
The level of uncertainty analysis (design-stage, advanced design-stage, …) in the result
depends on the level of uncertainty values given or available. This problem solution provides
the propagation of uncertainty from the variables to the result. PROBLEM 5.14
