1. A 240 mm dia. steam pipe, 200 m long is covered with 50 mm of high temperature insulation of thermal conductivity 0.092 W/m-K and 50 mm low temperature insulation of thermal conductivity 0.062 W/m-K. The inner and outer surface temperatures are maintained at 340°C and 35°C respectively. Calculate the following in SI unit: a. the total heat loss per hour, b. the heat loss per m² of pipe surface, c. the heat loss per m² of outer surface,
