Lab 3 Pressure: For the given Piston Diameter and weight, calculate the Piston Area in square inches in cell C5, then determine the total weight on the Piston in pounds in
column C for Increasing and column J for Decreasing. Calculate the Actual pressure in Pounds Per Square Inch in column D for Increasing and column K for Decreasing.
Determine the gage error in column E for Increasing and column K for Decreasing. Finally calculate the percent error (%) in column F for Increasing and column L for
Decreasing.
