Mercury is stored in a parallelepiped-shaped vessel. With what force does it press on its bottom measuring 10cm x 15cm if the level of mercury in the vessel is 20 cm? Mercury density 13600 kg / m3
Given:
a = 0.1m
b = 0.15m
h = 0.2m
q = 13600kg / m ^ 3.
F-?
Decision :
F = mg
m = qV = q * a * b * h
F = q * a * b * h * g = 13600 * 0.1 * 0.15 * 0.2 * 10 = 408H
Answer: 408N.
