Question details

Problem 1.022 An overhead 25-m-long, uninsulated industrial steam pipe of 200-mm diameter is routed through a building whose pipe surface temperature of 225 c, and the coefficient associated with natural convection is h10 W/m-K.1 (a) What is the rate of heat loss from the steam line? wals and air are at 25°C. Pressunized steam maintains a he surface emissivity is0.8 generated in a gas-fired boller operating at an emoency of,y = 0.90 and natural gas is pnced at G-so.02 per M, what a the annualcost a heat oss from the line?
