Heat Transfer Double pipe heat exchangers are preferably useful, when High viscosity liquid is to be cooled A corrosive liquid is to be heated Requirement of heat transfer area is low Overall heat transfer co-efficient is very high High viscosity liquid is to be cooled A corrosive liquid is to be heated Requirement of heat transfer area is low Overall heat transfer co-efficient is very high ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer As the difference between the wall temperature and bulk temperature increases, the boiling heat transfer co-efficient continues to increase goes through a minimum continues to decrease goes through a maximum. continues to increase goes through a minimum continues to decrease goes through a maximum.

Heat Transfer A process stream of dilute aqueous solution flowing at the rate of10 Kg.s⁻¹ is to be heated. Steam condensate at 95°C is available for heating purpose, also at a rate of 10 Kg.s⁻¹. A 1 - 1 shell and tube heat exchanger is available. The best arrangement is Counter flow with process stream on tube side Parallel flow with process stream on tube side Parallel flow with process stream on shell side Counter flow with process stream on shell side Counter flow with process stream on tube side Parallel flow with process stream on tube side Parallel flow with process stream on shell side Counter flow with process stream on shell side ANSWER DOWNLOAD EXAMIANS APP
