Unstable chemicals have been stored in a blastproof storage unit with concrete walls in an area distant from a chemical plant where the chemicals are used. On a hot day, the air temperature has reached deg C and the wind is blowing such that the heat transfer coefficient on the exterior wall surfaces area is WmKThe cm thick walls had been at deg C but something has caused the chemicals inside to ignite. Monitoring instruments indicate that the interior room temperature quickly reached and stabilized at deg C The walls of the storage unit have a thermal conductivity of WmK density kgm and specific heat capacity of JkgKFind the temperature profile through a wall, assuming that at time t the temperature of the left face interior is raised to oC while the right face exterior is exposed to blowing air at oCEstimate the time required to approach steady state using the explicit method with the following conditions:a nodes in this system with a time step of sb nodes in this system with a time step of sc How do the answers change with Should a time step even smaller be used to get an accurate answer or was s adequate?
