Calculate the heat flow through a 1.500m long copper bar with a cross sectional area of 3.00 cm2. One end at 2.0 degrees Celsius and the other end at 99.0 degrees Celsius.
Ok, remember the constant (k) of copper : 385 ( W/m*K) H dQ / dt k*A*(Tw - Tc) / L L lenght A area H 385*3*10^-2*(97) / 1.5 H 746.9 (J / s) Hope that helps
That's not all the physics in playIf you answered this example you could be wrong even if they tell you you are right. Two examples that have to be considered in the answer is 1. Is copper bar vertical or Horizontal. 2. Room Temp. at time of flow rate check.( example -30 F deg. or outside in 115 F degree temp.)
