According to Folsom [6], the capillary rise (Delta h) (in.) of a waterair interface in a tube
Question:
According to Folsom [6], the capillary rise \(\Delta h\) (in.) of a waterair interface in a tube is correlated by the following empirical expression:
\[\Delta h=A e^{-b \cdot D}\]
where \(D\) (in.) is the tube diameter, \(A=0.400\), and \(b=4.37\). You do an experiment to measure \(\Delta h\) versus \(D\) and obtain:
What are the values of \(A\) and \(b\) that best fit this data using Excel's Trendline feature? Do they agree with Folsom's values? How good is the data?
