Heat Transfer The critical radius 'r' of insulation on a pipe is given by r = k/2h r = h/k r = k/h r = 2k/h r = k/2h r = h/k r = k/h r = 2k/h ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer The variation of thermal conductivity of a metal with temperature is often correlated using an expression of the form K = K₀ + at. where, K is the thermal conductivity and T is the temperature (in °K). The units of 'a' in SI system will be W/m W/m.k None, A is just a number W/m.k² W/m W/m.k None, A is just a number W/m.k² 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 Equal to 45°C Less than 45°C Initially decreases and remains constant thereafter More than 45°C Equal to 45°C Less than 45°C Initially decreases and remains constant thereafter More than 45°C ANSWER DOWNLOAD EXAMIANS APP
Heat Transfer Air is to be heated by condensing steam. Two heat exchangers are available (i) a shell and tube heat exchanger and (ii) a finned tube heat exchanger. Tube side heat transfer area are equal in both the cases. The recommended arrangement is Finned tube heat exchanger with air outside and steam inside Shell and tube heat exchanger with air inside tubes and steam on shell side Shell and tube heat exchanger with air on shell side and steam inside tubes Finned tube heat exchanger with air inside and steam outside Finned tube heat exchanger with air outside and steam inside Shell and tube heat exchanger with air inside tubes and steam on shell side Shell and tube heat exchanger with air on shell side and steam inside tubes Finned tube heat exchanger with air inside and steam outside ANSWER DOWNLOAD EXAMIANS APP
