    Calculating Convective Heat Loss for Unclothed Person

    I plugged in the wrong h and thinking i was getting the result for another h. Thanks again Chestermiller. Great explanation. This thread can be closed.

    Calculating Convective Heat Loss for Unclothed Person

    I understand what you mean. In any case, I still don't understand the difference in terms (left side not corresponding to the right side). I'm also curious if my answer is correct.

    How Does Breathing Affect Water Vaporization and Caloric Loss?

    Inhaled Water Vapor Density = (17.3*.5) = 8.65g/m3? 10 liters = .01m3 8.65g/m3 * .01m3 = .0865 grams? 44g/m3 * .01m3 = .44 grams? Inhaled Water Vapor - Exhaled Water Vapor = -.3535 grams (Water Vapor leaving the body)? Would anyone mind giving me confirmation that I am going...

    Calculating Convective Heat Loss for Unclothed Person

    Using P = h*A*ΔT, given: h = 12 A = 1.5 ΔT = -11, (23 - 34) P = -99 However, I am confused about my units. I see that Chestermiller says Power doesn't exactly correlate to heat transfer, and when I look at my units of measure, I get the following: P = h*A*ΔT (watts) =...

    How Does Breathing Affect Water Vaporization and Caloric Loss?

    Homework Statement If a person breathes 10 liters per minute of air at 68°F & 50% relative humidity, how much water per minute must the internal membranes supply to saturate this air at 98.6°F? If all of this moisture is subsequently exhaled, how much water per day is given off by the body...

    Calculating Convective Heat Loss for Unclothed Person

    Homework Statement Heat is convected away from an object at the rate given by the following formula: ΔQ / Δt = h*A*ΔT Calculate the rate of convective heat loss in watts for an unclothed person standing in air at 23°C. Assume that the skin temperature is 34°C and that the body surface...

    Help Find the Area Between 3 Curves

    Mark, Thanks for your quick reply. Our instructor never taught us anything about using strips. All the homework problems up to this one in this section involved a few steps (for 2 curves). 1. Find Intersecting Points. 2. Use the x-coordinates as the upper and lower x that will be substituted...
