question_answer 6)

Torricelli's barometer used mercury. Pascal duplicated it using French wine of density \[984\,kg\,{{m}^{-3}}\]. Determine the height of the wine column for normal atmospheric pressure.

Answer:

\[p=0.76\times (13.6\times 103)\times 9.8=h\times 984\times 9.8\] or \[\rho =1\cdot 0\times {{10}^{3}}kg{{m}^{-3}}\]
