- 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
- Understanding pressure in terms of force - Physics Stack Exchange
"Basically is pressure the net normal force on a surface per unit area?" I don't think we use the word 'pressure' like this If the pressure of the air in an 'empty' bottle is atmospheric we wouldn't say that there is zero pressure on its walls, just because there is the same pressure inside as outside, so equal and opposite normal forces on a given area of wall
- 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
- Question #eb2c2 + Example - Socratic
The SI unit of pressure is the Pascal (Pa), and I will show some conversions from other non-SI units to Pa hereunder 1 Kilopascal (kPa) = 1000 pascal (Pa), ie 1kPa=1000Pa since kilo is the SI prefix for 10^3 Thus to convert from KPa to Pa, multiply by 1000 Example, 101,3kPa=101300Pa I have used this specific example since this represents standard air pressure at sea level and is also given
- 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
- 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
