Heat Transfer Maximum water velocity in tubes of a 1-2 shell and tube heat exchanger may be around __________ metres/second. 1 20 30 10 1 20 30 10 ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In a heat exchanger with steam outside the tubes, a liquid gets heated to 45°C, when its flow velocity in the tubes is 2 m/s. If the flow velocity is reduced to 1 m/s, other things remaining the same, the temperature of the exit liquid will be Initially decreases and remains constant thereafter Less than 45°C Equal to 45°C More than 45°C Initially decreases and remains constant thereafter Less than 45°C Equal to 45°C More than 45°C 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 tube side Counter flow with process stream on tube side Parallel flow with process stream on shell side Counter flow with process stream on shell side Parallel flow with process stream on tube side Counter flow with process stream on tube side Parallel flow with process stream on shell side Counter flow with process stream on shell side ANSWER DOWNLOAD EXAMIANS APP
