Chapter 22, Problem 1RQ
Why do some condensers have to be cleaned with brushes and others with chemicals?
Expert Solution & Answer
To determine
The reason behind the different methods of cleaning used for condensers.
Explanation of Solution
As per the problem statement, it is given thatsome condensers have to be cleaned with brushes and others with chemicals.
A condenser is a device, which is used to remove heat of the refrigerant. Condenser has tubes inside it through which the refrigerants flow. The tubes have very good coefficient of heat transfer.
Over period, the heat transfer coefficient decreases due to formation of scales and unwanted sediments in the tubes. At this time it has to be cleaned. In some condensers the tube are straight and can be easily detachable. In that type of condensers, cleaning is done using brushes.
In some condensers, the tubes are bend and welded. These tubes are not detachable and cleaning them using brush is not possible. In that case cleaning is done using chemicals.

You are working as an engineer in a bearing systems design company. The flow of
lubricant inside a hydrodynamic bearing (p = 0.001 kg m-1 s-1) can be approximated
as a parallel, steady, two-dimensional, incompressible flow between two parallel plates.
The top plate, representing the moving part of the bearing, travels at a constant speed,
U, while the bottom plate remains stationary (Figure Q1). The plates are separated by
a distance of 2h = 1 cm and are W = 20 cm wide. Their length is L = 10 cm. By
applying the above approximations to the Navier-Stokes equations and assuming that
end effects can be neglected, the horizontal velocity profile can be shown to be
