Question: A 2-cm-diameter glass rod 6 cm long [k = 0.8 W/m C] has a base temperature of 100C and is exposed to an air

A 2-cm-diameter glass rod 6 cm long [k = 0.8 W/m ∙ ºC] has a base temperature of 100ºC and is exposed to an air convection environment at 20ºC. The temperature at the tip of the rod is measured as 35ºC. What is the convection heat-transfer coefficient? How much heat is lost by the rod?
