Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient Can flow either inside or outside the tubes Flows through the tube Flows outside the tubes Should not be used as it gives very high pressure drop Can flow either inside or outside the tubes Flows through the tube Flows outside the tubes Should not be used as it gives very high pressure drop ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The Sieder-Tate correlation for heat transfer in turbulent flow in pipe gives Nu α Re0.8, where, Nu is the Nusselt number and Re is the Reynolds number for the flow. Assuming that this relation is valid, the heat transfer co-efficient varies with the pipe diameter (D) as (D)1.8 (D)0.2 (D)-0.2 (D)-1.8 (D)1.8 (D)0.2 (D)-0.2 (D)-1.8 ANSWER DOWNLOAD EXAMIANS APP
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 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 Counter flow with process stream on tube side Parallel flow with process stream on tube side 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 Giving the surface a mirror finish Roughening the surface Painting the surface black Painting the surface white (with aluminium paint) Giving the surface a mirror finish Roughening the surface Painting the surface black Painting the surface white (with aluminium paint) ANSWER DOWNLOAD EXAMIANS APP
