1. To avoid overheating, natural convection analysis is to be considered. If the minimum allowable heat transfer due to natural convection is 30 W, find the maximum angle at which the TV can hang off the wall (0 < 0 < 60). Some temperatures were collected; Back panel surface: 45 °C, ambient: 32 °C. A typical 55-inch TV screen measures (122 cm x 69 cm).

1. To avoid overheating, natural convection analysis is to be
considered. If the minimum allowable heat transfer due to
natural convection is 30 W, find the maximum angle at which
the TV can hang off the wall (0 < 0 < 60). Some temperatures
were collected; Back panel surface: 45 °C, ambient: 32 °C. A
typical 55-inch TV screen measures (122 cm x 69 cm).
Note: A typical screen uses a portion of the incoming energy to light up the LED panel, while the rest is
dissipated as natural heat convection.
