Ok, now i normally hate it when I see people who have obviously copied out a mathematics question that they have been given by school or college and posted it in yahoo answers.
But I am basically teaching myself manometers after my rubbish lecturer missed it out of the curriculum completely. This is the question I am stuck with, i don't know where to start!
If the mercury barometer reads 780mm what will be the atmospheric pressure in:-
A) meters of water
B) meters of oil of a relative density 0.8
C) in KN/m2
Relative density of Mercury = 13.6
mass density of water = 100kg/m3
Ans: A)10.6m B)13.25m C) 104KN/m2
Please can someone give me some info on how to complete this question.
