Heating Effect of a Fan A room is initially at the outdoor temperature of 25°C. Now a large fan that consumes 200 W of electricity when running is turned on (Fig. 2–49). The heat transfer rate between the room and the outdoor air is given as \dot{Q}=U A\left(T_{i}-T_{o}\right) \text { where } U=6 W / m ^{2} · °C is the overall heat transfer coefficient, A = 30 m² is the exposed surface area of the room, and T_{i} \text { and } T_{o} are the indoor and outdoor air temperatures, respectively. Determine the indoor air temperature when steady operating conditions are established.
