Heat Transfer In a forward feed multiple effect, the pressure build up will be least at the outlet of the last effect least at the inlet of the first effect highest at the inlet of the last effect highest at the outlet of the last effect least at the outlet of the last effect least at the inlet of the first effect highest at the inlet of the last effect highest at the outlet of the last effect ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The heat transfer by radiation from a mild steel surface is to be reduced by reducing the emissivity of the surface. This can be best achieved by Painting the surface white (with aluminium paint) Roughening the surface Painting the surface black Giving the surface a mirror finish Painting the surface white (with aluminium paint) Roughening the surface Painting the surface black Giving the surface a mirror finish ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Economy of a multiple effect evaporator is not influenced much by the rate of heat transfer temperature of the feed boiling point elevations ratio of the weight of the thin liquor to thick liquor rate of heat transfer temperature of the feed boiling point elevations ratio of the weight of the thin liquor to thick liquor ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer A 2-4 heat exchanger involves Both counter and parallel-flow of the fluids Only parallel-flow of fluids Smaller pressure drop compared to 1-2 exchanger Only counter-flow of fluids Both counter and parallel-flow of the fluids Only parallel-flow of fluids Smaller pressure drop compared to 1-2 exchanger Only counter-flow of fluids ANSWER DOWNLOAD EXAMIANS APP
