Process Equipment and Plant Design Steam economy is defined as the amount of evaporation per unit amount of steam used, while the capacity is the total evaporation obtained per hour. Use of multiple effect in evaporation Increases economy Increases capacity Does not affect the capacity Both B & C Increases economy Increases capacity Does not affect the capacity Both B & C ANSWER DOWNLOAD EXAMIANS APP
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 Either A or B Neither A nor B Cap pitch of 1.3-2 times the cap diameter Clearance of 25-75 mm Either A or B Neither A nor 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 Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid Results in higher shell side pressure drop Can accomodate less number of tubes for a given shell diameter Creates relatively lower turbulence on the shell side resulting in lower shell side heat transfer co-efficient Facilitates easier shell side cleaning; hence is more suitable for handling high dirt factor shell side fluid ANSWER DOWNLOAD EXAMIANS APP
