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 tube side Counter flow with process stream on shell side Counter flow with process stream on tube side Parallel flow with process stream on shell side Parallel flow with process stream on tube side Counter flow with process stream on shell side Counter flow with process stream on tube side Parallel flow with process stream on shell 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 Roughening the surface Giving the surface a mirror finish Painting the surface black Painting the surface white (with aluminium paint) Roughening the surface Giving the surface a mirror finish Painting the surface black Painting the surface white (with aluminium paint) ANSWER DOWNLOAD EXAMIANS APP
