In Table 22.214.171.124, the atmospheric correction factor is absolute enclosure pressure above sea level divided by absolute pressure at sea level. You can interpolate the above table for 14000 ft above sea level. The equation for finding the interpolated value can be written as y = y1 + ((x – x1)/(x2 - x1) * (y2 - y1)) X = 14,000 ft X1 =…
