During heavy exercise, the body pumps 2.00 L of blood per minute to the surface, where it is cooled by $2.00^{\circ} {C}$. What is the rate of heat transfer from this forced convection alone, assuming blood has the same specific heat as water and its density is 1050 ${kg} / {m}^{3} ?$
$\frac{Q}{t}=0.29 \mathrm{kW}$

in number 52. They said that when exercise to leaders of blood is pumped to the surface every minute at the surface, it's cooled two degrees and were asked to find What is the He trained the rate of heat transfer that happens for that. I'm so rate of heat transfer so he transfer per time. That would be a rate. Um, we're told that blood has the same density because, um, we're told this is the density of the blood, and we're told has the same specific heat as water. So Q is the mass tend to specific heat times the change in temperature. And this could be per time. I don't know mass, but I do know the volume, and I'm given the density. And remember that density is mass per volume, so mass would be a density times of all you setback appeal. Substitute that. And so instead of mass, I'm gonna have a density per volume still claims the specific heat times of change in temperature all over time. I just need to make sure everything's in the right units now for this to turn out to be a Jule per second or what So my density that snort units 10 50. The volume that's in leaders. I know there's 1000 leaders leaders is one meter cubed, So this would be to thousands of meter cubed. So my voice, I'm going to say his point. 002 Some specific heat, they said, is the same as the water I need. That's being Jules per kilogram degree Celsius. So that's 41 86. They told me the temperature change would be two degrees and it changed. The blood moved two liters per minute. So I'm going to My time here Has to be in seconds, though. That would be 60. So I'm not quite. I divide they get 293. What?
