WebWater Flow Recommendations - BV Thermal Systems WebJun 1, 2024 · With an effective temperature range of 40 to 200°F (4 to 93°C), water is the first fluid to consider. The process flow is as important – if not more important – as the process temperature. The higher the flow, the more likely heat transfer will occur. Two types of flow can occur inside a pipe or heat exchanger: laminar and turbulent.
