A quick estimate of surface heat dissipation – hope this helps!
Thread Content
For tanks and pipes containing chemical materials or fluids, the heat loss to the atmosphere can be estimated using the formula: q = (T0 – Ta) × αs, where T0 is the external surface temperature of the tank or pipe in °C, Ta is the ambient temperature in °C, and αs is the surface heat transfer coefficient in W/(m2·°C). The value of αs can be calculated as αs = 11.62 + 6.97√υ, with υ representing the average annual wind speed in m/sec; for indoor conditions, αs is taken as 11.62 W/(m2·°C). This method can also be adapted for calculating the evaporation rate from ponds (pollution sources) in environmental engineering applications.
It’s quite useful. Could the original poster provide some more derivation steps?
Is it related to the surface finish or color of the device?
Thank you to the original poster; this formula is very useful
Same question: what is the scope of application for this formula? Source?
