According to the provided measurements, which pressure corresponds to 2.4" hg?

To determine which pressure corresponds to 2.4" hg, it is important to understand the relationship between inches of mercury (hg) and pressure measurements, particularly in terms of atmospheric pressure. In this case, 2.4 inches of mercury must be converted to a gauge pressure or absolute pressure in the correct units.

Typically, the conversion from inches of mercury to pressure in psi (pounds per square inch) involves using the fact that 1 inch of mercury is approximately equal to 0.491 psi. Therefore, when multiplying, we have:

2.4" hg x 0.491 psi/inch hg = 1.1774 psi.

After establishing the equivalent psi, it can then be assumed that this value is being assessed against known pressures in the choices presented.

In this context, the number that correlates with the converted value is 13.47 psi, which reflects the lower pressure reading in context with the other options. This implies that 13.47 psi may represent a baseline for gauge pressure measurement when accounted for in relation to the atmospheric pressure.

Thus, identifying the correct pressure reading corresponding to 2.4" hg lies in understanding the appropriate conversions and how that translates into the selections provided, confirming
