Solved Convection ovens operate on the principle of inducing
Mechanical Engineering questions and answers. Convection ovens operate on the principle of inducing forced convection inside the oven chamber with a fan. A small cake is to be baked in an oven when the convection feature is disabled. For this situation, the free convection coefficient associated with the cake and its pan is hfr = 3 W/m^2/K.
