A displacement transducer has the following specifications Linearity error ±0.1% of reading, Drift ±0.15%/C of reading, sensitiv
ity error ±0.25% of reading, excitation 10-25 V DC, output 0-5 V DC, range 0-5 cm. The output is to be indicated on a voltmeter with accuracy of ±0.15% of the reading and has a resolution of 10 µV. The system will be used at "room temperature" which can vary by as much as 5C. Estimate the design stage uncertainty in a 3.5 cm reading assuming 95% confidence. Read your book to learn more details about this.

Given data:
Diffusion constant for nitrogen is
Diffusion flux
concentration of nitrogen at high presuure = 2 kg/m^3
location on which nitrogen concentration is 0.5 kg/m^3 ......?
from fick's first law
Take C_A as point on which nitrogen concentration is 2 kg/m^3
Assume X_A is zero at the surface
