Heat Transfer The radiation heat flux from a heating element at a temperature of 800°C, in a furnace maintained at 300°C is 8 kW/m². The flux, when the element temperature is increased to 1000°C for the same furnace temperature is 12.0 kW/m² 11.2 kW/m² 14.6 kW/m² 16.5 kW/m² 12.0 kW/m² 11.2 kW/m² 14.6 kW/m² 16.5 kW/m² ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Extremely large or small volumes of fluids are generally best routed through the shell side of a shell and tube heat exchanger, because of the Less corrosion problems High heat transfer co-efficient Flexibility possible in the baffle arrangement Low pressure drop Less corrosion problems High heat transfer co-efficient Flexibility possible in the baffle arrangement Low pressure drop ANSWER DOWNLOAD EXAMIANS APP
