What is the rate of heat transfer in a steel pipe with a diameter of 10 cm and a length of 2 meters, if hot water with a temperature of 80°C is flowing through it at a rate of 5 liters per minute and the ambient temperature is 20°C? (Assume uniform heat distribution and neglect any heat loss from the pipe)
