PENGARUH PERUBAHAN ALIRAN TERHADAP KOEFISIEN PERPINDAHAN PANAS PADA HEAT EXCHANGER JENIS SHELL AND TUBE (THE EFFECT OF CHANGES IN THE FLOW OF HEAT TRANSFER COEFFCENT IN HEAT EXCHANGER TYPE SHELL AND TUBE)

Heat exchanger is the equipment used for heat transfer between two or more fluids . As a tool for the exchange of heat from the fluid with a high temperature fluid to the low temperature , a heat exchanger is expected to have a heat transfer coefficient ( Uc ) as appropriate . Theoretically increase in the flow rate will lower the price of the heat transfer coefficient ( Uc ) itself . From this phenomenon , wants to study the influence of fluid velocity of heat to the heat transfer coefficient ( Uc ) at a Shell and Tube Heat Exchanger . The result showed that the increased rate of hot fluid at a temperature of hot fluid entry is kept constant , the heat transfer coefficient ( Uc ) decreases.
