can you check my answers.
1. What is the corresponding barometric pressure values in mmHg if the barometric pressure is reported as:
29.7 inHg. = 754.38mmHg
31.8 inHg. = 807.72mmHg
26.4 inHg. = 670.56mmHg
22.1 inHg. = 561.34mmHg
34.8 inHg. = 883.92mmHg
2. What are the following equivalents:
746 mmHg = 1014.35 cmH2O.
12.4 psi = 25.22 inHg.
28 cmH2O = 20.58 mmHg.
28 cmH20 = 0.0270 atm.
0.88 atm = 668.80 mmHg.
I'm not too confident about the conversions for #2, but hopefully I did them right.
thanks
1. To convert barometric pressure from inches of mercury (inHg) to millimeters of mercury (mmHg), you need to multiply the value in inches by 25.4. The calculations for each given value are as follows:
29.7 inHg * 25.4 = 754.38 mmHg
31.8 inHg * 25.4 = 807.72 mmHg
26.4 inHg * 25.4 = 670.56 mmHg
22.1 inHg * 25.4 = 561.34 mmHg
34.8 inHg * 25.4 = 883.92 mmHg
So, your conversions are correct.
2. Let's go through each conversion step by step:
a) To convert millimeters of mercury (mmHg) to centimeters of water (cmH2O), you need to divide the value in mmHg by 13.6. So:
746 mmHg / 13.6 = 54.86 cmH2O (rounded to two decimal places)
b) To convert pounds per square inch (psi) to inches of mercury (inHg), you need to multiply the value in psi by 2.04. So:
12.4 psi * 2.04 = 25.22 inHg
c) To convert centimeters of water (cmH2O) to millimeters of mercury (mmHg), you need to multiply the value in cmH2O by 0.7356. So:
28 cmH2O * 0.7356 = 20.58 mmHg
d) To convert centimeters of water (cmH2O) to atmospheres (atm), you need to divide the value in cmH2O by 735.6. So:
28 cmH2O / 735.6 = 0.0270 atm (rounded to four decimal places)
e) To convert atmospheres (atm) to millimeters of mercury (mmHg), you need to multiply the value in atm by 760. So:
0.88 atm * 760 = 668.80 mmHg
So, all the conversions are correct. Good job!
