A large plane, perfectly insulated on one face and maintained at a fixed temperature T 1 on the bare face, has an emissivity of 0.84 and loses 250 W/m2 when exposed to surroundings at nearly 0 K. The radiant heat loss from another plane of the same size is 125 W/m2 when bare face having emissivity 0.42 and is maintained at temperature T 2 is exposed to the same surroundings. Subsequently these two planes are brought together so that the parallel bare faces lie only 1 cm apart and the heat supply to each is so regulated that their respective temperatures T 1 and T 2 remains unchanged. Determine he net heat flux between the planes
The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1: A single device can heat fluids without requiring an electrical element. S6: Because there is no electrical element, there is no risk of fire, so the system is suitable for dangerous environments. P: A heat exchanger transfers heat from the central cavity to an air heater, a water heater or an industrial processor. Q: It has a container like the crankcase of a car’s engine, which contains the fluid to be heated. R: Compression and friction at the nozzles heat the fluid so that the temperature in the central -cavity rises steadily. S: A motor and pulley inside the container turn a rotor wheel, which in turn forces the fluid again and again through narrow nozzles into a central cavity. The proper sequence should be
