Hot oil at 120 degrees Celsius is pumped through a circular
aluminum pipe of diameter 1 meter and wall thickness 0.05 meter.
the speed of the oil being pumped results in a heat transfer
coefficient of 1500 W/m^2K. The pipe is insulated with a 0.4 meter
thick wrap made of some close to gypsum plaster. Length of 4
meters of the pipe passes through a small pond of water at
temperature 288 K with a convective heat transfer coefficient of
250 W/m^2K. What is the heat transfer rate to the pond?
