Finding the Space Between Lead Shots

Plan 1

By Mass

Lead Shot

1 - Empty box, m ₁

2 - Box filled with Lead, m ₂

3 - Box filled with Lead and H ₂ 0, m ₃

4 - Box filled with H ₂ 0, m ₄

m _Pb = m ₂ - m ₁

V _Pb = (m ₂ - m ₁) / ρ _Pb

m _{H 2 0} = m ₃ - m ₂

V _{H 2 0} = (m ₃ - m ₂) / ρ _Pb = V _SP (The space between the lead)

ratio = V _Pb / V _tot

Plan 2

By Volume

1 - V _{H 2 0 1} = V _tot

2 - V _{H 2 0 2} = V _SP

V _Pb = V _tot - V _SP

R = V _Pb / V _tot = (V _tot - V _SP) / V _tot => 1 - (V _SP / V _tot)

Experiment

Plan 1

We had 2 scales to measure the weight. Let's call them scale #1 and scale #2, measurement on them were called weight #1 and Weight respectively.
