Unformatted text preview: k =115 W/m K) 7.5 mm thick if the temperature at the two faces are 150 and 50 o C; assume steady-state heat flow. (b) What is the heat loss per hour if soda-lime glass (( k =1.7 W/m K) instead of brass is used? 3. The heat capacity for an ideal crystalline solid is 3 R , where R is the gas constant. The heat capacity for Al is 900 J/kg K. What percentage deviation is this value from the ideal value of 3 R ?...
