Process Equipment and Plant Design In the allocated cap area, bubble caps are generally arranged on equilateral triangular pitch. Number of caps fixed on a plate is with a Neither A nor B Either A or B Cap pitch of 1.3-2 times the cap diameter Clearance of 25-75 mm Neither A nor B Either A or B Cap pitch of 1.3-2 times the cap diameter Clearance of 25-75 mm ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a shell and tube heat exchanger, triangular pitch arrangement as compared to square pitch arrangement Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Results in higher shell side pressure drop Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Can accomodate less number of tubes for a given shell diameter Results in higher shell side pressure drop ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design Of the pressure vessels, with same thickness but different diameters, which one withstands higher pressure? Strength of the vessel is same irrespective of the diameter Smaller dia vessel Larger dia long vessel Larger dia vessel Strength of the vessel is same irrespective of the diameter Smaller dia vessel Larger dia long vessel Larger dia vessel ANSWER DOWNLOAD EXAMIANS APP
