For a boiler at a power plant, heat must be transferred to boiling water inside of pipes at a rate of 3.00 gigaWatts. The boiling water passes through copper pipes that have a wall thickness of 4 millimeters and a surface area of 0.12 square meters per meter length of the pipe. Find the total length of pipe (there are actually many pipes in parallel) that must pass through the furnace if the steam temperature is 225 degrees Celsius and the external temperature of the pipes is 600 degrees Celsius.
