//Variable declaration:
D = 1.0 //Diamete of vessel (ft)
L = 1.5 //Length of vessel (ft)
T1 = 390.0 //Surface temperature of vessel (°F)
T2 = 50.0 //Surrounding temperature of vessel (°F)
h = 4.0 //Convective heat transfer coefficient (Btu/h.ft.°F)
pi = %pi
//Calculation:
A = pi*D*L+2*pi*(D/2)**2 //Total heat transfer area (ft^2)
Q = h*A*(T1-T2) //Rate of heat transfer (Btu/h)
R = 1/(h*A) //Thermal resistance (°F.h/Btu)
//Result:
printf("The thermal resistance of vessel wal is : %.4f °F.h/Btu.",R)
