Question #304627

A temperature sensor may be modeled as a sphere having a thermal conductivity of 91 W/m-K, a density of 8900kg/m3, and a specific heat of 444J/kg-K. If the sphere diameter is 3 mm. Determine the time required for the sensor to respond to 95% of a step change in the


temperature of the convective environment. The heat transfer coefficient is 1000W/m2-K.
