Heat Transfer In a shell and tube heat exchanger, The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance The relationship is not generalised The temperature drop is inversely proportional to the resistance across which the drop occurs The temperature drops in the two fluids and the wall are proportional to individual resistances There is no relationship between temperature drop and resistance ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer In Joule's experiment, an insulated container contains 20 kg of water initially at 25°C. It is stirred by an agitator, which is made to turn by a slowly falling body weighing 40 kg through a height of 4 m. The process is repeated 500 times. The acceleration due to gravity is 9.8 ms⁻². Neglecting the heat capacity of agitator, the temperature of water (in °C) is 25 26.8 40.5 34.4 25 26.8 40.5 34.4 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 Parallel flow with process stream on shell side Counter flow with process stream on tube side Counter flow with process stream on shell side Parallel flow with process stream on tube side Parallel flow with process stream on shell side Counter flow with process stream on tube side Counter flow with process stream on shell side ANSWER DOWNLOAD EXAMIANS APP
