Why water is not suitable to be used in barrometer?
If water is used hight of water colomn would be very high.
Which measuring device used in cooking or candle making options are barrometer wind vane thermometer or rain gage?
glass tube
If the barrometer rises does the temperature rise?
The precipitation does NOT cause the rise or fall in the barometer. However precipitation is more usually associated with an atmospheric depression (a cyclone) and thus a fall in the barometer will usually FORETELL precipitation.
Formula of pressure?
hydrostatic pressureP= hdgwhere;p= pressure (N/m2 or Pa)h=height (m)d= density (kg/m3)g= acceleration due to gravity(9.81 m/s2)e.g.example problem.a pressure gage register 40 psig in a region where the barrometer is 14.5 psia. fine the absolute pressure in psia., and kPa(KN/m2)give.Pg= 40 psiaPo= 14.5 + 40p=54.5b. P=54.5psia=54.5 lb.....6894.8 N/m2In2 1 psi=37576606 N/m2375.77 KNp= 375.77 KPa
