Calculate the overall heat-loss coefficient for a solar collector with a single glass cover having the following specifications (neglect edge effects):
Spacing between the plate and the cover 5 cm
Plate emittance 0.2
Glass emittance 0.88
Ambient air temperature 283 K
Back insulation thickness 3 cm
Conductivity of back insulation material 0.04 W/(m.K)
Mean plate temperature 340 K
Collector tilts 45°
Wind - heat transfer coefficient 10 W/(m2.K)
What are semiconductors? Give an example for n-type semiconductors. Semiconductors are materials having electrical conductivity among that of insulators and conductors. This i
Q. Define: Electric flux. Give its unit. The electric flux is described as the total number of electric lines of force crossing through the given area and its unit is Nm 2 C-1
give applications of resonance
Q. What is Maser? Give the principle of it. 1) The term MASER for Microwave Amplification through Stimulated Emission of Radiation. 2) The working of maser is similar to th
UNIFORM ACCELERATION: If velocity of a body alters by equal amounts in equivalent intervals of time, then the body is said to have uniform acceleration. OR If average a
Two waves of equal frequency have amplitudes 2 units and 3 units respectively. When they superpose coherently the intensity of the resultant wave is I 1 . The intens
Explain the production of Newton's ring because of reflected light with a neat diagram. Get the expression for the diameter of both dark and bright ring.
A solid substance has a molar volume which is smaller than that of its liquid phase. Which of the following statements regarding the solid-liquid phase transition is/are true?
a) Orbital movement of electrons b) On the source of orbital motion of electrons c) These are repelled in an external magnetic field i.e. have a tendency to g
It is based on the principle that conductivity of a semiconductor enhances with increase in the intensity of incident light. In this, a thin layer of some semiconductor (as
