We conducted an experiment to determine the relationship between the heat transfer coefficient for forced convection over a cylindrical rod due to varying air flow velocities. The relationship that was found was plotted with the heat transfer coefficient on the Y axis and the air flow velocity on the X axis. The question then asks to graph the dimensionless ratio(which we calculated for all ten test which we ran) as the parameter. So I have the list of dimensionless values that correspond to each of the ten tests that we ran but I don't know how to apply this dimensionless number to the graph as a parameter.
- What does this mean?
- What is a Parameter on a graph?
- How would I go about plotting something that is dimensionless, when both the x and y axis clearly have units?
