The document contains multiple engineering problems related to heat transfer. Problem 1 calculates the heat loss per meter of a steam pipe covered with an insulating coating. Problem 9 calculates the heat loss from an electric furnace with firebrick walls and a quartz window. Problem 5.2-1 involves calculating the time for a copper wire to cool from an initial to final temperature under different convection coefficients. Problem 4.3-4 calculates the heat loss and steam condensed per hour for an insulated steam pipeline.
