Good Example Of Essay On Pdx:
The experiment was conducted for a period of 20 days and targeted the days were there was rain and fog to get the variation in atmospheric pressure. The other atmospheric pressure records were collected from PDX. The histogram shows the comparison between the recordings of the Bennett Barometer and the Barometer in PDX.
Average = 30.0735
Standard Deviation = 0.26802
The average pressure for the PDX for the first 20 records is 30.0735. The standard deviation is 0.26802 for the PDX for the first 20 records. The average pressure for the Barometer for the first 20 records is 12.46575. The standard deviation is = 0.142855 for the Barometer for the first 20 records. The mean measurements are different, the barometer is observed to have a leakage at a rate of 2mm/hr, which can be presumed to be a reason for different readings for the two.
The average mean between the two measurements is at 30.13 for the PDX and 12.49 in the Bennett Barometer. The standard deviation of the two measurements shows a greater relationship. The barometer pressure in both the barometric pressure and the Bennett Barometer readings show almost the same recordings. The barometer pressure in both the barometric pressure and the Bennett Barometer readings show almost the same recordings. The atmospheric pressure of a place depends on the weather that is exhibited; fog and rain determine whether there is a high or low atmospheric pressure. In this case the direction of wind was determined by the level of atmospheric pressure in the weather. The days with fog shows a low atmospheric pressure showing that the strength of wind was also weak.
