A simple procedure for measuring surface convection heat transfer coefficients involves coating the surface with a thin layer of material having a precise melting point temperature. The surface is then heated and, by determining the time required for melting to occur.
The convection coefficient is determined. The following experimental arrangement uses the procedure to determine the convection coefficient for gas flow normal to a surface. Specifically, a long copper rod is encased in a super insulator of very low thermal conductivity, and a very thin coating is applied to its exposed surface. If the rod is initially at 25°C and gas flow for which h = 200 W/m2 · K and T8 = 300°C is initiated, what is the melting point temperature of the coating if melting is observed to occur at t = 400 s?
A meteorologist uses a pitot -static tube to measure the wind speed in a tornado. Based on the damage caused by the storm, the tornado is rated as EF5 on the enhanced Fujita Scale. This means that the wind speed is estimated to be in the range of 261..
