Heat transfer coefficent

An air conditioner condenser in an automobile consists of 2 of tubular heat exchange area whose surface temperature is SOT. Saturated refrigerant-134a vapor at S0°C hjf = 152 kJ/kg) condenses on these tubes. What heat transfer coefficent must exist between the tube surface and condensing vapor to produce 1.5 kg/min of condensate ... 

We also recall that a balance on the coolant gives the variation of coolant t peraturc with axial distance where t/, is the overall heat transfer coeffic and R is the reactor wall radius...
