Concept explainers

Free Damped Vibrations

Free vibration is a type of vibration in which the external force is removed after giving the initial displacement to a body/system. In other words, in this type of vibration, force is applied at the initial displacement of the system, and after the initial displacement, force is removed, and the system vibrates at the natural frequency.

--------Q.1// A conference room is to be air conditioned for comfort conditions of (25oC) DBT and (50% RH). The outdoor air conditions are (35oC DBT) and (28oC WBT). The sensible and latent heat are (43200 kJ/hr) and (36000 kJ/hr) respectively. The return air from the conference room is mixed with outdoor air before entering the cooling coil as shown in the Figure below. In addition, the return air from the (conference room) is mixed with cooling air (after cooling coil) see Figure below, where cooling coil by bass factor (BPF = 0.1) and (ADP =10oC).
