+//Variable declaration:
+h = 48.0                    //Convective heat transfer coefficient (Btu/h.ft.°F)
+A = 2*1.5                   //Total heat transfer area (ft^2)
+Ts = 530.0                  //Surface temperature of plate (°F)
+Tm = 105.0                  //Maintained temperature of opposite side of plate (°F)
+kW = 3.4123*10**3           //Units kW in a Btu/h
+
+//Calculation:
+Q = h*A*(Ts-Tm)             //Heat transfer rate in Btu/h (Btu/h)
+Q1 = Q/kW                   //Heat transfer rate in kW (kW)
