Question
Assuming we have steady state condition and one-dimensional heat transfer in the system, determine the following: The convection heat transfer rate, radiation heat transfer coefficient
Assuming we have steady state condition and one-dimensional heat transfer in the system, determine the following:
The convection heat transfer rate, radiation heat transfer coefficient (hRad ), radiation heat transfer rate, and the combined heat transfer rate (natural convection plus radiation) from the outer surface of the bare pipe and each insulating material with different thicknesses. Provide a summary table
please show steps and explanation.
(I have posted other questions regarding the same lab, you may want to refer to the answers of those questions)
The effect of insulator thickness on the heat transfer rate from a pipe is investigated. High pressure steam is passing through a 3 -inch schedule 40 pipe, which is covered with insulating layers of different thickness. Apparatus: - Steam in the tube; 3-inch schedule 40 pipe (inner dimeter: 0.077927 m; and, outer diameter: 0.088900m ) - Thermocouples connected to different points of the setup - Insulating material has emissivity of 0.9; pipe has emissivity of 0.8 - Thermal conductivity of insulating material is 0.102W/m.K Experimental procedure: Turn on the temperature reading panel to collect temperature values of different points of the setup| (Figure 1) at evenly distributed time intervals until getting steady values (steady state condition). - Heat Loss trom an Insulated Pipe Figure 1.
