Name(s) : Siddharth Sukhwal Purdue Email Address(es): Section #: 10 Assignment #: Homework 8 Problem 3 I/We have not used material obtained from any other unauthorized source, either modified or unmodified. Neither have I/we provided access to my/our work to another. The project I/we am/are submitting is my/our own original work. Linear Regression of Fuel Pump Calibration Table Input Section: Output Section: Fuel Flow Rate (gpm) Boost Pump Voltage (V) 3. Assumption for all modeling - all data points for fuel flow rate = 0 can be dropped from the data set since the 0 0 the pump would not be operating (or "on") at this flow rate. The (0,0) data points skew the model. 0.19 3 0.27 4 5. Hand selected points: (0.43,11) and (0.21,4) yields Voltage = 31.8*DesiredFlowRate - 2.67 0.33 6 m= (11-4)/(0.43-0.21)= 31.8 b = 11-31.8*0.43= -2.674 0.41 9 0.45 10 6. The least squares computed equation is: Voltage = 28.66*DesiredFlowRate - 2.05 0.49 12 0.00 0 7. The computed r^2 value is 0.95 0.17 2 0.25 4 8. See plot below for Excel's linear regression trendline and r^2 value
