Calculate the force exerted by a pressure of $ 50 \; mbar $ on a surface of $4\;cm^2$
Solution (Click):
Conversion to $Pa$: ..........$50\;mbar$ $=$ $50\cdot 10^{-3}\;bar$ = $50\cdot 10^{2}\; Pa$
Calculation of force in $N$: ..........$F=P\cdot S$ $=$ $50\cdot 10^{2}\;Pa \cdot 4\cdot 10^{-4}\cdot m^2$ = $2\;N$
