In an experiment, the temperature of a hot gas stream is to be measured by a thermocouple with a spherical junc-tion. Due to the nature of this experiment, the response time of the thermocouple to register 99 percent of the initial tem-perature difference must be within 5 s. The properties of the thermocouple junction are k = 35 W/m⋅K, rho = 8500 kg/ m 3 , and c p = 320J/kg⋅K. If the heat transfer coefficient between the thermocouple junction and the gas is 250 W/ m 2 ⋅K, deter-mine the diameter of the junction.

1in2 processor chip can be modelled as an isothermal plane wall of silicon, isothermal on both sides. the power input to the bottom of the plane wall, or the processing power of the chip, often called the thermal design power (tdp), is 100w. assume the periphery is adiabatic. the silicon is 400 microns thick. the temperature at the junction, or in this case on the bottom of the isothermal plane wall, is 85°c. what is the top surface temperature, assuming that the only mode of heat transfer is conduction
