How to Calculate Heat Flow Rate through Cylindrical Composite Wall of 2 Layers?
Heat Flow Rate through Cylindrical Composite Wall of 2 Layers calculator uses Heat Flow Rate = (Inner Surface Temperature-Outer Surface Temperature)/((ln(Radius 2/Radius 1))/(2*pi*Thermal Conductivity 1*Length of Cylinder)+(ln(Radius 3/Radius 2))/(2*pi*Thermal Conductivity 2*Length of Cylinder)) to calculate the Heat Flow Rate, The Heat flow rate through cylindrical composite wall of 2 layers formula is defined as the rate of heat flow through a cylindrical composite wall of 2 layers in when the inner and outer surface temperatures, thermal conductivities, length of the cylinder, and radius of each layer are known. Heat Flow Rate is denoted by Q symbol.
