Question 75 - Review - Chapter 1

Problem:

An epoxy paint for painting a ship's hull must be applied with a distribution of 1 liter per 8 $m^2$

Question:

How thick is the layer of freshly applied paint?

Solution:

One Liter = $1 dm^3 = 10^{-3} m^3$

So we have to determine the height of a body with a surface of 8 $m^2$ and a volume of $1x10^{-3}m^3$

$height = \frac{volume}{surface}$

# Berekeningen
Volume = 1e-3
Surface_m2 = 8
Height = Volume / Surface_m2
print('The Height = Volume in m2 / Surface per m2')
print(f'    So: {Volume:.2g} / {Surface_m2:.2g} = {Height:5.5g} m of {Height*1e6:5.2f} µm')

The Height = Volume in m2 / Surface per m2
    So: 0.001 / 8 = 0.000125 m of 125.00 µm
