From a determined project an air conditioning of 36.000 Btus (10.64 KW). At the first step, the performance of the radiator fins must be analyzed using the following parameters /assumptions:• The air conditioner is operated with R410A refrigerant• Refrigerant enters the heat exchanger at a temperature of 6°C• The tubes (of the refrigerant), made of copper, have an outside diameter of 6 mm• Round fins are attached, made of aluminum, with a constant section of 1 mm and an efficiency of 3• Fin tips are adiabatic• With the fan on, the convection coefficient is 20 W/(m² K)
Determine:• The number of fins required for heat transfer calculated in the first part• The airflow velocity required to achieve the convection coefficient of  = 20 W / (m² K) (can beconsidered an external flow over the fin)• The convection coefficient and the heat flux in the event of a fan failure (in free convection), thefins can be considered flat walls oriented vertically
