Problem 1: Calculate radiation view factor F1-3 for the following configuration: \[ \pi:=5 \quad L:=3 \quad H:=2 \] Problem 2: A circular grill has a \( 30 \mathrm{~cm} \) diameter. The coals in the bottom of the grill are \( 950 \mathrm{~K} \), the mesh at the top is covered with steaks at \( 5^{\circ} \mathrm{C} \). The coals and mesh are \( 20 \mathrm{~cm} \) apart. For this problem assume both the coals and steaks are blackbodies. Determine the initial rate of radiation heat transfer from the coals to the steaks. How far apart do the coals and steaks need to be so that \( 50 \% \) of the energy from the coals reaches the steaks?
