'Pressurized steam flows through a pipe of 0.6 m diameter: The pipe is embedded in a concrete block ,conductivity k = 1.4 W/mK ,with a square Cross sectional length; W = 1 The required surface temperature values are 401 and 301 in K Calculate the heat loss from the pipe per unit length:
T1
Concrete
T2
D = 0.6 m'
