g Calculate a better value for the convection coefficient using resources from heat transfer. Assume forced convection of the air inside the chimney moving at 4 ft/s. Assume convection on the outside of the chimney is due to natural convection. Use the temperature plots or probe of the inside and outside surfaces to calculate the bulk fluid temperature and obtain accurate material properties for air based on these temperatures. Hint: Your new results for h should on the same order of magnitude of the value I provided. If it isn't, check your units. Update to you calculated values for h and resolve your model.
