Kerosene enters a 5 cm diameter tube at 35C with a velocity of 3 m/s. The tube is wrapped with a resistance heating element so that when it is energized a uniform heat flux is imposed on the tube. At the exit of the tube, the temperature of the kerosene is to be 45C. A constraint is placed on the process, such that the local kerosene temperature cannot exceed 80C; this is likely to occur at the wall of the...

Blood flows at 0.0065 kg/s through an artery of diameter 8 mm and length 350 mm. It enters the artery at 36.5°C and leaves it at 34.0°C. Calculate the rate of heat transfer from the blood, the mean heat flux through the artery wall, and the mean velocity of the blood. (Note: the thermophyhsical properties of blood may be approximated by properties of liquid water at 37°C.)

Combustion gases passing through a 2.3-cm-internal diameter circular tube are used to vaporize waste water at atmospheric pressure. Hot gases enter the tube at 115 kPa and 250°C at a mean velocity of 5 m/s, and leave at 150°C. If the average heat transfer coefficient is 120 W/m2 °C and the inner surface temperature of the tube is 112°C, determine the tube length. Answer in cm with two(2) decimal places.
