Process Equipment and Plant Design Spherical shaped pressure vessel is considered to be the most ideal, because it can Withstand higher pressure for a given metallic shell thickness Be designed without wind load considerations Be fabricated very easily Be supported very easily Withstand higher pressure for a given metallic shell thickness Be designed without wind load considerations Be fabricated very easily Be supported very easily 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 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 Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop 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 Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design In a cylinderical vessel subjected to internal pressure, the longitudinal stress σL and the circumferential stress, σh are related by σh = σL No relation exists σh = σL/2 σh = 2 σL σh = σL No relation exists σh = σL/2 σh = 2 σL ANSWER DOWNLOAD EXAMIANS APP
Process Equipment and Plant Design High pressure fluid in a shell and tube heat exchanger should preferably be routed through the Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop Shell side, if the flow is counter-current and tube side if the flow is co-current Shell side for large overall heat transfer co-efficient Tubes to avoid the expansion of high pressure shell construction Shell side for smaller total pressure drop ANSWER DOWNLOAD EXAMIANS APP
