Radioactive wastes are temporarily stored in a spherical container, the center of which is buried a distance of 10 m below the earth's air-soil surface. the outside diameter of the container is 2.0 m, and 500 w of heat are released as a result of radloactive decay. if the soll surface temperature is 25*c, what is the outslde surface temperature of the contalner?

Outside temperature =88.03°C

Explanation:

Conductivity of air-soil from standard table

   K=0.60 W/m-k

To find temperature we need to balance energy

Heat generation=Heat dissipation

Now find the value

We know that for sphere

Given that q=500 W

so

By solving that equation we get

=88.03°C

So outside temperature =88.03°C

answer: copyright is extremely important to authors because it constitutes the ownership of one's original work. having ownership means you can protect your work as intellectual property and control who makes money from it—which is you and those to whom you assign rights.
