Awalrus transfers energy by conduction through its blubber at the rate of 150 w when immersed in −1.00ºc water. the walrus’s internal core temperature is 37.0ºc , and it has a surface area of 2.00 m^2. what is the average thickness of its blubber, which has the conductivity of fatty tissues without blood? (answer in cm)

t=12.6 cm

Explanation:

Given that

Q= 150 W

T₁ =  −1.00ºC

T₂ = 37.0ºC

A= 2 m²

Lets take thermal conductivity of blubber

K= 0.25 W/(m.K)

Lets take thickness = t

We know that heat transfer due to conduction given as

t=0.126 m

t= 12.6 cm

Therefore thickness of the blubber is 12.6 m.

here are some information of the future of geothermal energy:

-the future of geothermal energy can pretty much be summed up with a single word: more

-scientists plan in going deeper than 120 meters

-we are hoping that one day, we will get all of our energy from renewable energy sources such as geothermal energy

hope this !
