Hose Volume and Drain Time

Geometric hose volume only (V = pi x (d/2)^2 x L). Actual drain time depends on measured flow, slope, and conditions, and is not calculated here.

ℹVerify locally before acting. This tool is a planning and arithmetic aid, not a substitute for training, local SOPs, calibrated instruments, or scene assessment. Confirm critical values independently. Suite status: DRAFT - not yet department-approved for operational use.
When you'd use this: Estimating how much water is sitting in a charged line during overhaul/cleanup, or sizing how much water a long supply lay itself will hold before it's even flowing.
