Show transcribed image text 6. A cylindrical steam pipe passes through a chemical plant, where wind passes in cross-flow over the outside of the pipe. The steam is saturated at 14.55 bar and you can assume that the resistances to heat transfer inside the pipe and of the pipe itself are minimal, so that the outside surface temperature of the pipe is equal to the saturation temperature of the steam. The pipe is stainless steel and has an outside diameter of 6.75 cm and a length of 29.5 m. The air flows over the pipe at 6.0 m/s and has a bulk fluid temperature of 27 °C. A. What is the rate of heat transfer from the pipe to the air? B. Would your answer change if the air flow direction changes to parallel flow? If so, calculate that q as well Note: You may need to interpolate values for fluid properties to match the film temperature.
