Conduction and Convection

When energy travels from one object to another it is said to have undergone heat transfer. Heat transfer is nothing but the transfer of thermal energy or internal energy from one thing to another, like e.g., when a vessel with water, kept on top of a burner, heats up because of the flame underneath it.

Question

For a collector having the following characteristics, calculate the fin efficiency and the collector efficiency factor:

Overall loss coefficient = 8 W/m2 °C.
Tube inside diameter = 10 mm.
Tube spacing = 150 mm.
Plate thickness = 0.5 mm.
Tube outside diameter - 10,5 mm.
k = 385 W/m °C
Heat transfer coefficient inside the tubes = 300 W/m2 °C.
Bond conductance = co W/m. °C
