Required chilled-water tank volume calculator

Convert delivered ton-hours to water volume after allowing for useful temperature range and capacity losses.

Units
V=12,000×C×1008.34×dT×uV = \frac{12{,}000 \times C \times 100}{8.34 \times \mathit{dT} \times u}

Worked example

Given

  • CC = 800 ton·h
  • dT\mathit{dT} = 18 Δ°F
  • uu = 90 %
V=12,000×800×1008.34×18×90≈71,054V = \frac{12{,}000 \times 800 \times 100}{8.34 \times 18 \times 90} \approx 71{,}054
