Assuming full ventilation the same pressure as atmospheric outside the building at the time. An open fire or solid-fuel stove will reduce it very slightly by the convection up the chimney, so it will draw in air from outside.
In the room will usually be the same as the outside atmospheric pressure. The standard atmosphere is defined as being 101325 pascals = 101.325 kPa.
About one "bar" or one "atmosphere" which is about 15 psi or 760.001 mm-Hg.
Obviously this will go up and down a little as the weather changes.
The pressure of water increases about 0.445 psi per foot of depth. If we "zero" our meter so we have "no" pressure at the surface (ignoring the normal 14.7 psi of air pressure at sea level), at 18 feet we will have 0.445 psi/ft times 18 feet, which is 8.01 psi, or right at about 8 psi.
8.51 g/l at standard temperature (0 degrees Celsius,) but 7.93 g/l at room temperature (20 degrees Celsius). 1.251 g/l * 1 ATM / (100 psi * .0680459639 ATM/psi) = 8.51 g/l 1.251 g/l * 1 ATM / (100 psi * .0680459639 ATM/psi) / (293 K / 273 K) = 7.93 g/l
It is at room temperature.
Approximately 3.56 psi.
the normal boost is 5-12 psi. the normal vac is about 18-20 psi
Normal is 30 psi. Minimum is 7 psi.
Normal. Should only be able to hit 80 psi with very cold to cold oil though.
The stock tires are usually 35 psi
Normal compression on a gasoline engine is about 125 psi.
30 psi cold
Probably 5 psi to 60 psi.
100 psi to 140 psi.
Over 20 psi at idleUnder 80 psi while driving Over 20 psi at idleUnder 80 psi while driving
V6 is 40 psi, four cylinder is 15 psi.
