Engine oil flows at a rate of 0.05 kg/s through a section of a 2.5 cm diameter tube. The oil enters the section at a temperature of 50C. The tube wall is kept at 20 C, and it can be assumed that the flow through the section is fully developed. The section of the tube is 5 m long. (a) What is the exit temperature of the oil? (b) What is the heat transfer rate from the oil to the tube wall?
