Heat Transfer Extended heat transfer surface like fins are used to increase the heat transfer rate. Fin efficiency is defined as the ratio of heat transferred across the fin surface to the theoretical heat transfer across an equal area held at the Average temperature of the fin Constant temperature equal to that of the base Surrounding temperature Temperature of the fin end Average temperature of the fin Constant temperature equal to that of the base Surrounding temperature Temperature of the fin end ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Convective heat transfer co-efficient in case of fluid flowing in tubes is not affected by the tube length/diameter ratio, if the flow is in the __________ zone. laminar None of the listed here highly turbulent transition laminar None of the listed here highly turbulent transition ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Indirect contact heat exchangers are preferred over direct contact heat exchangers, because Cost of equipment is lower There is no mist formation There is no risk of contamination Heat transfer co-efficient are high Cost of equipment is lower There is no mist formation There is no risk of contamination Heat transfer co-efficient are high ANSWER DOWNLOAD EXAMIANS APP
