Question

Convert the following pressure readings from inches of mercury units to psi and Pascal units:

a. 28.5 · inHg


b. 30.5 · inHg

Answer 1

To convert pressure from inches of mercury to psi and Pascal units, use the conversion factors 0.4912 psi/inHg and 3,386.389 Pa/inHg, respectively. For 28.5 inHg the conversions are 14.00 psi and 96,512.08 Pa, while for 30.5 inHg they are 14.98 psi and 103,334.87 Pa.

Step-by-step explanation:

Converting pressure readings from inches of mercury (inHg) to pounds per square inch (psi) and Pascals (Pa) involves using conversion factors. To convert from inHg to psi, the conversion factor is approximately 0.4912 psi/1 inHg. To convert to Pascals, we use the fact that 1 inHg is approximately equal to 3,386.389 Pa.

• a. To convert 28.5 inHg to psi, multiply by the conversion factor: 28.5 inHg x 0.4912 psi/inHg = 14.00 psi.
• To convert 28.5 inHg to Pascals, multiply by the conversion factor: 28.5 inHg x 3,386.389 Pa/inHg = 96,512.08 Pa.
• b. To convert 30.5 inHg to psi, multiply by the conversion factor: 30.5 inHg x 0.4912 psi/inHg = 14.98 psi.
• To convert 30.5 inHg to Pascals, multiply by the conversion factor: 30.5 inHg x 3,386.389 Pa/inHg = 103,334.87 Pa.
