In the question, we have given conductivity is 0 .59 watt per meter kelvin.
00:08
Alpha is 0 .141 into 10 to the power minus 6 meter square per second.
00:15
Rho is given as 999 kilogram per meter cube.
00:20
Heat capacity cp is given as initial temperature is 30 degree celsius.
00:26
The infinity is 7 degree celsius.
00:29
After heating, the surface temperature is 7 .3 degree celsius.
00:35
Center temperature is 10 degree celsius.
00:39
The diameter of the tomato is 8 centimeter.
00:44
The number of the tomato is 8.
00:47
Now, we are assuming tomatoes are completely sphere.
00:52
Second, heat conduction is 1d.
00:55
Third, thermal properties are constant.
00:59
Now, we have to check if one term approximation solution is applicable or not.
01:06
For that, we have to find the fourier number.
01:10
Fourier number tau is alpha t by r square.
01:15
We have t as 2 or which is 0 .6345 greater than 0 .2...
