//Variable declaration:
Di = 0.902/12.0 //Inside diameter of tube (ft)
Do = 1.0/12.0 //Outside diameter of tube (ft)
k = 60.0 //Thermal conductivity of tube (Btu/h.ft^2..)
//Calculation:
//From example 15.19:
a = 0.00126
Dr = (Do - Di)/2.0 //Radial thickness of tube wall (ft)
Rw = Dr/k //Resistance of wall (Btu/h..)
ho = 1.0/(a-Rw) //The revised ho (Btu/h.ft^2..)
//Result:
printf("The revised ho is : %.0f Btu/h.ft^2.. .",ho)
