Question

Determine the rate of heat flow through flat wall of thickness 0.5 m when the two surfaces are maintained at 1000°C and 100°C respectively. The thermal conductivity of the material of the wall can be taken as a function of temperature in the form K = 1.0 (1 + 0.001 t) kcal/hrm2 °C​

Answer 1

Explanation:

Polytetrafluoroethylene is a synthetic fluoropolymer of tetrafluoroethylene that has numerous applications. The commonly known brand name of PTFE-based compositions is Teflon™ by Chemours, a spin-off from DuPont, which originally discovered the compound in 1938.
