The barometric pressure measured outside an airplane at 3 km ( ft) was 524 mmHg. Calculate the pressure in kPa.

69.8609 KPa.

Explanation:

The following data were obtained from the question:

Pressure (in mmHg) = 524 mmHg.

Pressure (in KPa) =?

Thus we can obtain the pressure in KPa as follow:

760 mmHg = 101.325 Kpa

Therefore,

524 mmHg = 524 mmHg × 101.325 KPa / 760 mmHg

524 mmHg = 69.8609 KPa

Thus, 524 mmHg is equivalent to 69.8609 KPa.

i just calculated it all out, and not including weekends, and all the different days off. as of this school year (2018-2019) students are spending 2198 hours in school this year
