he fan shown in Figure 6 blows air at the rate of 5700ft3/min. The fan weighs 35 lb and has its center of gravity at G. The specific weight of air is γ = 0.076lb/ft3. Assume that the upstream velocity of air is zero. Determine: (a) The force exerted by the fan on the air. (b) The pressure rise across the fan blades in psi. (c) The power required by the fan. (1 horsepower = 550 lb-ft/s)

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. 0.69 m
