For GATE CH Paper A$P!RANT$ : ------------------------------------------------------------ Subjects : Plant Design. Question : 1(a). For a cylindrical internally pressurized vessel, which of the following closure types would withstand highest pressure if each closure is of the same material and thickness ? (A) Hemispherical (B) Ellipsoidal (2:1) (C) Conical (D) Flat plate ------------IFFCO GET 2013 Prelims 1(b). For a 1-1 fixed tube sheet heat exchanger, the following data are given, Design inside pressure : Shell side = 10^3 kN/m^2 ; Tube side = 2 * 10^3 kN/m^2 ; Design temperature : Shell side = 50 deg C ; Tube side = 150 deg C; Allowable stress value at both design temperatures is 1.2 * 103 kN/m^2 . Shell inside diameter = 0.6 m, corrosion allowance (for shell and headers)= 3*10^-3 m and joint efficiency = 1. Find to the nearest mm, 1(b) The shell thickness. 1(c) The header shell thickness. Answers follow as the comments line up or check on the next day. --------------------------------------------------------- - MOHSIN KHAN https://facebook/BORN.IMMORTAL Visit >> targate.in Join https://facebook/groups/targate.in/
