DHI Lay-Flat Hose Freeze Potential Calculator
This calculator estimates static freeze time and flowing-line freeze potential for exposed lay-flat TPU hose. It includes hose diameter, length, flow rate, water temperature, air temperature, wind speed, salinity, and safety factor.

Notes
Engineering note: This calculator is intended as a field screening tool. It estimates when water reaches the salinity-adjusted slush/freezing point and gives a practical freeze-risk indication. It should not be treated as a final engineering certification for line blockage, because actual freezing depends on hose flattening, ground contact, solar gain, cycling, nucleation, insulation, and field operating conditions.
