Heat Loss Factors and Graphs Watlow

The pipe is emitting heat through radiation. The heat emitted can be calculated thanks to the following formula : Q/A = 0.1713 * ε * [(Ts/100)4 - (Ta/100)4] With : Q = heat loss (BTU/h) A = heat transfer area (ft2) Ts = surface temperature (R) Ta = air temperature (R) ε = emissivity of the pipe See more The heat loss from an uninsulated pipe is basically made of 2 components : the heat loss through radiation and the heat loss through convection. Total heat loss = radiation heat loss + convection heat loss See more The convection depends on the air velocity (wind speed), there are 2 cases for the calculation, either the wind speed is = 0, or the wind speed is > 0 See more The total loss of heat is thus the sum of the heat loss through radiation and the heat loss through convection. Total heat loss = radiation heat … See more WebJan 10, 2024 · Heat loss of an insulated pipe vs an uninsulated pipe RT=12πhR2L=2.27. ϕ=(80−20)RT=27.3 for the insulated pipe. ϕ=(80−20)RT=26.4 for the uninsulated pipe. … setup factory 9.5 full
