Question: How much heat is lost in one hour through a 15 cm x 3.7m x 6.1m concrete floor if the inside temperature is 22 degrees c and the ground temperature is 13 degrees c?
some info:
thermal conductivity of concrete=1.1
change in temperature=8
Relative Equations:
kAchangeT/L
Attempt at problem:
1.1(.15x3.7)(22-13)/6.1
this is not giving me the right answer. the answer should be 5.363E6J
can someone explain to me what I am doing wrong.
thanks
