A carbon steel plate (thermal conductivity = 45 W/moC) (600 x 900 x 25) mm2 is maintained at 310oC. Air at 15oC bellows over the hot plate.If convection heat transfer co-efficient is 22 W/moC and 250 W is lost from the plate surface by radiation, Determine the inside plate temperature.

Three similar coils, each having a resistance of 8Ω and an inductive reactance of 8Ω are connected (a) in star and (b) in delta, across a 415V, 3-phase supply. Calculate
Natural and forced vibrations When we strike a tuning fork with a rubber hammer it vibrates with certain frequency. The frequency does not change even if we hit it harder.
Static Electricity: 1. There are two types of charges positive and negative. 2. Like charges repel and unlike charges attract each other. 3. Charged bodies make electric
