Heat Transfer The advantage of backward feed multiple effect evaporators over forward feed units is that There is no additional cost of pumping Equal heat transfer co-efficients exist in various effects Most concentrated liquid is at highest temperature Heat sensitive material can be handled There is no additional cost of pumping Equal heat transfer co-efficients exist in various effects Most concentrated liquid is at highest temperature Heat sensitive material can be handled 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 40.5 26.8 25 34.4 40.5 26.8 25 34.4 ANSWER DOWNLOAD EXAMIANS APP
