Temperature effects in flat-bed flows

WebThe effect of temperature on τ o and q sb is shown by the data. For R *b < 20 increase in the temperature of a flow results in a decrease in τ o and τ *b and an increase in R *b, q sg and q *b. For 20 < R *b < 200 an increase in water temperature results in an increase in τ ob, τ *b … Web1 Jun 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.
