Question:

a) Calculate the heat flux through a sheet of brass 7.5 mm (0.30 in.) thick if the temperatures at the two faces are 150°C and 50°C (302°F and 122°F); assume steady-state heat flow.

(b) What is the heat loss per hour if the area of the sheet is 0.5 m2 (5.4 ft2)?

(c) What will be the heat loss per hour if soda-lime glass is used instead of brass?

(d) Calculate the heat loss per hour if brass is used and the thickness is increased to 15 mm (0.59 in.)
