Ahouse in logan, utah has no central air conditioning system. daytime temperatures in the summer regularly exceed 32°c (90°f) but nighttime temperatures are cool. a logan
homeowner wishes to install a fan with diameter 0.5 m in the ceiling of her home to withdraw air from the interior of her house at night and discharge it outside of the house,
which will pull the cooler night air in through her open windows. the interior volume of her home is 720 m^3 . if she wishes air within her home to be exchanged fully at least every 20 min, calculate:
a. the minimum flow rate of the fan in m^3/s
b. the mean discharge air speed in m/s.
