A pipeline has a length of 750 m and is made of steel with a 2-inch diameter schedule 40 and a k of 26 Btu/hr foot F and leads saturated steam at 300F. Features 1/2-inch perlite insulation expanded, with a k = 0.033 Btu/hr ft F Heat is lost by drafting and convection to the environment which is at a temperature of 70F and with a combined transfer coefficient of color of 10.3 Btu/hr F. If the heat coefficient inside the pipe is 34.7 Btu/hr F What will be the heat loss with and without insulation?
