In the landing gear for the Airbus 320, engineers wish to design a damper (a device for reducingvibrations) consists of a metal plate 1mm thick moving centrally between two large plates. The gapsbetween the plate sides and side walls are both equal to 1mm. The area of the central plate is 4x10-4m2, and the damper is filled with liquid having a dynamic viscosity of 7.63poise. Calculate thedamping force on the central plate if the later moves at a velocity of 0.7m/

Work and Heat Transfer

It is generally related to thermal engineering which tells about the use, creation, conversion and transfer of heat energy between the systems. It is also considered that to transfer heat from one source to another, transfer of masses is also required. There are various mechanisms by which, transfer of heat takes place i.e. thermal conduction, convection, radiation or by change of phase. All these mechanisms have their own specific features which sometimes occur simultaneously within the same system.
