a) On Tuesday, March 7, 2017, the maximum temperature reached in Los Angeles was 77 degree F. If the observed barometric reading was 30.15 inches of Hg, and the barometer was calibrated for 0 degree C, what should the corrected barometric pressure be, just taking the differential thermal expansion of glass and mercury into account? Use the correction table in Lecture Notes 3. You can use linear interpolation to find the proper correction, if the height of the mercury column is not precisely one that is tabulated: If c_1 is the correction for h_1 and c_2 is the correction for h_1 but the observed height h is between h_1 and h_2 then the correction should be c = c_1 + (c_2 - c_1) (h - h_1)/(h_2 - h_1). Note that 1 inch = 25.4 mm. b) On March 13, 2017, a barometric pressure reading was taken in Charlotte, North Carolina when the temperature was 32.0 degree F. The barometer was calibrated for a latitude of 45 degree. Charlotte, NC is located at 35.2 degree N latitude. If the observed barometric pressure was 30.17 inches of Hg, what should the corrected barometric pressure be, taking Charlotte's latitude into account?
