Air at 22°C is blown over a hot pipe with a surface area of 3.19 m2 to dissipate 927 W of heat energy. What is the minimum convection heat transfer coefficient that will ensure that the temperature of the pipe surface is less than 45°C [round your final answer to two decimal places]? T. Air, T.
A container holds 102.9 liters of Oxygen at 268.4K and a pressure of 1.95 atmospheres. How much heat is required to raise the temperature of this gas to 314.1K, holding the volume constant? Give your answer in kJ. Treat the gas as an ideal gas. Note: It is understood that your answer is in units of kilo-Joules, however do not explicitly include units in your answer. Enter only a number. If you do enter a unit ("kJ" in this case), you answer will be counted wrong.
