Apipe is to be buried in the ground. the temperature of the ground is 10°c at the start of the day. during daytime, there is heat flux on the surface due to solar radiation. if the temperature of the pipe is to be kept very close to the initial temperature 10°c, calculate how deep the pipe needs to be buried. use resources online and research articles to obtain the thermophysical properties of the ground required to do the calculation. the ground can be considered part of earth's crust. plot temperature as a function of depth inside the ground at the end of day. make assumptions as necessary.
