Which one Blows Harder?

Endurance Innovation is now on Patreon [https://www.patreon.com/enduranceinnovation]! Have a peek at our page and show us some love. * 3:30 Cycling Tips review of fans [https://cyclingtips.com/2022/02/tested-what-is-the-best-fan-for-indoor-training/] * Fan specs: volumetric flow rate, airflow velocity, power * Measured skin temp, core temp, heat flux * Used an array of Core body temp sensors  * Compared no fan, small desktop fan, low velocity air mover, wahoo headwind, scroll fan * Heat transfer equation: Q=k*A*ΔT, where Q is the heat transfer, k is  the heat transfer coefficient, A is the surface area, and ΔT is the difference between skin temperature and the air around the skin * Maximize all three variable to maximize heat transfer * Perception of thermal comfort vs core temperature * 39:30 how much does a flappy run top cost in terms of run power? * Tight clothing improves wicking and cooling * Based on a CdA of 1.0, at 4:00/km, aero drag is 40W * Flappy kit may increase CdA by 20% or 8W * Michael’s 4:00/km Stryd power is 340W, plus 40W for air resistance * So floppy kit hit of 8W is an increase of ~2% * @ a 5:00/km pace, the aero drag is too small to worry about.
