Question:
A rocket-engine nozzle is coated with a ceramic material having the following properties: k = 1.73 Btu/h ft °F, α = 0.35 ft2 /h. The convective heat-transfer coefficient between the nozzle and the gases, which are at 3000°F, is 200 Btu/h ft2 °F. How long after start-up will it take for the temperature at the ceramic surface to reach 2700°F? What will be the temperature at a point 1/2 in. from the surface at this time? The nozzle is initially at 0°F.
