3. Using the data of part B, plot the data and label. Y-axis is Resistance, X-axis is

tank level.

i. Answer here

a. From the mathematics that govern the geometry of the tank, describe why

the equation is fundamentally linear or non-linear.

b. Find a linear transfer function. Describe the error. Is this a good fit?

i. Answer here

c. Find a higher order transfer function. Describe the error. Is a higher

order fit justified?

i.

Answer here

d. This is a resistive sensor. In Lecture 8 we learned how to linearize it.

Would you suggest linearizing the output of the sensor based on the

transfer function?
