Answer :
Final answer:
To convert 72.55 kPa to inches of mercury (inHg), a proportion can be set up using the standard atmospheric pressure of 101.325 kPa which corresponds to 29.92 inHg. By cross multiplying and dividing, one can calculate the equivalent pressure in inHg.
Explanation:
The conversion from kilopascals (kPa) to inches of mercury (inHg) is part of the field of Physics, and involves understanding and applying the principles of fluid mechanics and pressure measurements. The standard conversion factor is established based on the fact that normal atmospheric pressure (1 atmosphere or ~101.325 kPa) can support a column of mercury about 760 mm (29.92 in.), making this a widely accepted standard reference.
Given the barometric pressure in Vancouver is 72.55 kPa and considering that an atmospheric pressure of 101.325 kPa equals 29.92 inches of mercury, you can use these values to calculate the pressure in units of inches of mercury. We can form a proportion to solve for the unknown value which in this case is the pressure in inHg:
(72.55 kPa / 101.325 kPa) = X inHg / 29.92 inHg
When you cross multiply and divide, the value of X will provide the equivalent pressure in inches of mercury.
To convert the barometric pressure from kilopascals (kPa) to inches of mercury (inHg), we can use the conversion factor that 1 kPa is approximately 0.2953 inHg. Given that the barometric pressure in Vancouver, Canada is 72.55 kPa, we can calculate the pressure in units of inches of mercury:
72.55 kPa x 0.2953 inHg/kPa = 21.4 inHg
Therefore, the pressure in Vancouver, Canada is approximately 21.4 inches of mercury (inHg).
