Q. Explain working of Tubesheets?
The tube and tube pitch selected shall be approved by WorleyParsons Canada. The preferred tube pitch shall be a minimum of 1.3 x tube OD and patterns shall be selected by fabricator with WorleyParsons Canada approval.
The tube inlets and tubesheet shall be protected from overheating and hot spots be refractory lined and ceramic tube inlet ferrules inserted as required. The ferrules to the tubes shall have smooth transitions to prevent discontinuity of boundary layers and turbulences. The inlet vena contracta must be entirely inside the ferrules. Ferrules shall not contact the tubes. Clearances are required for insulation and flexibility. Additional insulation may be obtained by wrapping with ceramic fiber papers.

Gathering Lines: A gathering line, also called a ladder track, is one into which a number of parallel tracks merge. This is shown in Figure. It is used in marshalling yards.
Find the Laplace transform of the following differential equation: ? +3? +6x = 0, x(0) =0, ?(0)=3 Taking the inverse Laplace transform of X(s), obtain the time solution x(t).
Calculate the force - pulley: A string is passing over a smooth pulley. The string supports the mass m on one side which is to be pulled up with acceleration a. calculate the
