Heat Transfer In an extended surface heat exchanger, fluid having lower co-efficient 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 Can flow either inside or outside the tubes Flows through the tube 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 26.8 25 34.4 40.5 26.8 25 34.4 40.5 ANSWER DOWNLOAD EXAMIANS APP
