Chapter 8, Problem 8.40P
A thin-film heat flux sensor has a sensitivity uV
3a= 5v. Consider using this heat flux sensor * W/m~ to measure heat flux such that the nominal voltage output is 40 pV The voltage output is measured by a nano-voltmeter having an uncertainty of 0.003% of the reading. The uncertainty in the sensitivity of the heat flux sensor is ±10% (this assumes the sensor is employed without local calibration). Determine the uncertainty in a measured heat flux having the parameters listed above.
