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.
What do you mean by thin prism? and What is the lateral shift given by a parallel sided glass slab for grazing incidence of light?
Q. In Young's double slit experiment, the width of the fringe obtained with light of wavelength 60000A is 2 mm. Calculate the fringe width if the entire apparatus is immersed in a
State concept of Charging by conducting Charging by conducting - transfer of charge among two objects through contact - objects have similar charge
EXAMPLES OF IT
It is described as the nature of charge potential of charge potential is of two types: (i) Positive potential: with respect to positive charge. (ii)Negative potential: with r
According to their frequencies, waves are separated into three categories: (1) Audible or sound waves : Range 20 Hz to 20 KHz. These are formed by vibrating bodies like as voc
The photon fluence rate is 10 7 photons mm -2 sec -1 for a beam of γ rays. One fourth of the photons have energies of 100 keV, one half have energies of 80 keV and the remaining
If each point of a surface is at similar potential, then it is known an equipotential surfac. or For a given charge distribution, locus of each and every positions having sim
Explain the differences between heat transfer mechanisms in solids, liquids, gases (conduction, convection, radiation) Explain the combinations of substances, in terms of molecula
