Process Equipment and Plant Design The wall thickness for a large high pressure pipeline is determined by the consideration of the Axial tensile stress in the pipe Forces exerted by static and dynamic action at bends Temperature stresses Circumferential pipewall tension Axial tensile stress in the pipe Forces exerted by static and dynamic action at bends Temperature stresses Circumferential pipewall tension 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 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 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 ANSWER DOWNLOAD EXAMIANS APP
