Define coefficient of restitution.

True/False Manual load calculations should be considered only for preliminary design or simple buildings.  Building occupants are often assume to liberate 500 Btuh, consisting of 250 Btuh sensible heat + 250 Btuh latent heat. If, for some reason, the occupants liberated 600 Btuh, consisting of 150 Btuh sensible heat + 450 Btuh latent heat, which of the following effects would occur? Select all that apply. A) Less refrigeration would be needed. B) More refrigeration would be needed. C) More air would be needed to cool the space. D) Less air would be needed to cool the space.
