Web6 de mar. de 2024 · The heating curve is constructed based on four pre-set temperature values. For the valve to operate correctly, the user defines the pre-set temperature (downstream of the valve) for 4 intermediate external temperatures: -20° C, -10° C, 0° C, 10° C. Each increase or decrease in temperature shifts the curve by a given value. Webthe heat flow density is determined, which represents a certain temperature difference or the temperature difference between the wall and the fluid for a certain heat flow rate. As an example, for free convective heat transfer from a vertical wall, (4.193) Eqs.
