How is formula for converting pressure from mmHg to Pa derived? Today my younger brother asked me from where does the 1 Pa = 0 00750061683 mmHg formula for mercury barometer come He needs a way to derive it, or an academic source which can be cited After d

Water in vacuum (or space) and temperature in space The atmospheric pressure at this altitude drops to about 0 032 Pa (wikipedia), which is still a lot more than outer space (less than $10^ {-4}$ Pa according to wikipedia) The phase diagram of water shows that, at this pressure level, water can exist only as a solid or as vapor, depending on temperature, but not as a liquid

fluid dynamics - Will just the increase in height of water column . . . It may appease the mind slightly to note that drawing a mere liter of water from your tank would drop the pressure from 981kPa down to just 9 81kPa On the other hand in a 100m high tower with a 1m^2 cross section throughout, drawing a liter of water from the tank would hardly reduce the pressure at all So although the pressure depends on the height of the water column and not the cross

weight - Where on Earth does the mass of 1 kg actually produce a 1 kg . . . Let's look at some widely used units of pressure: Pa, Bar, atm, kgf cm², mmHg, mmH₂O The first two are based on the SI system Numbers 2-4 (Bar, atm, kgf cm²) are within a few percent of each other but all are widely used The last three on the list all depend on the value of standard gravity in their definition
