14 cards from this deck
Volume of liquid passing through pipe per unit time
πr2×flow speed (cm/sec)\pi r^2 \times \text{flow speed (cm/sec)}πr2×flow speed (cm/sec)
Vol. of pipe segment, length = flow speed
Total volume ÷ volume per second
a3:b3a^3:b^3a3:b3
Volume has 3 dimensions, each contributes to scaling
V=πr2hV = \pi r^2 hV=πr2h
V=13πr2hV = \frac{1}{3}\pi r^2 hV=31πr2h
V=43πr3V = \frac{4}{3}\pi r^3V=34πr3
V=23πr3V = \frac{2}{3}\pi r^3V=32πr3
