Thermal conductivity of the wetsuit

AI Thread Summary
To estimate heat loss from a person in a 3mm wetsuit immersed in 10ºC water, the thermal conductivity (k) of the wetsuit material is essential. The formula for calculating power loss is k * area * temperature difference / thickness, with an estimated body area of 2m². Wetsuits are typically made of Neoprene, which has a thermal conductivity range of 0.15-0.45 W/m*k. This information can be found on various physics resources online. Accurate calculations will help determine the heat loss effectively.

hi,


I would appreciate any help i could get on this, thanks.


I've to estimate the heat loss from a person, immersed in water at 10ºC if he is wearing a 3mm wetsuit

did anyone know how to process?


thanks a lot

Science news on Phys.org
look up the thermal conductivity (k) of the suit material (W/mk)
Then power = k * area * temperture difference /thickness

You normally estimate the area of a body as 2m^2
 
thanks

but where can i find the wetsuit conductivity (clothing for watersport)?

Diving suits are usually made of Neoprane, according to the site below the thermal conductivity is: 0.15-0.45 W/m*k.

Been around 40 years since I took basic physics in college and while I remember doing some examples of insulation values / energy conduction, I doubt I could to the math now even if I could find the formulas. I have some some corrugated plastic sheet (think of the plastic signs you see on the side of the road) that is used in bee hives. Also have some used in a green house though a bit different in dimensions than this example but the general approach should still apply. Typically, both...
Problem: You’re an Uber driver with a Tesla Model 3. Today’s low: 30F, high: 65F. You want to reach a USD$ profit target in the least number of hours, but your choices could have added cost. Do you preheat the battery only when you are headed to the charging station (to increase the charging rate by warming the battery — however the battery might not be “warm enough” when your reach the charger and thus slower charging rates), or do you always “navigate to the charger” the entire day (which...
Thread 'Is Callen right in claiming dQ=TdS for all quasi-static processes?'
Hello! I am currently reading the second edition of Callen's Thermodynamics and an Introduction to Thermostatistics, and I have a question regarding Callen's definition of quasi-static. On page 96, Callen says: Another way of characterizing Callen's definition is that a process is quasi-static if it traces out a continuous curve in the system's configuration space. So far it's all well and good. A little later, Callen claims that the identification of $$TdS$$ as the heat transfer is only...
