Why heat sinks are black anodized?

Radiative heat transfer (heat transfer by electromagnetic radiation) is proportional to e*(T1^4 - T2^4) where T1 is the absolute temperature of the material, T2 is the absolute temperature of the surroundings, and e is the emissivity coefficient. A black material has a high emissivity coefficient, while a silvery material has a low emissivity coefficient. However, the emissivity coefficient cuts both ways, so to speak. A black material in thermodynamic equilibrium with its environment absorbs more radiation, true. But it also emits more radiation (this is necessary for equilibrium to hold). Likewise, a silvery material absorbs less radiation, and also emits less radiation. Conductive heat transfer ensures that the black material on the surface of the heat sink remains hot. The surroundings are at a lower temperature. Therefore T1 and T2 are set, and the heat transferred from the heat sink to the surroundings is simply proportional to e, the emissivity coefficient.

Why is the coefficient of discharge of a venturimeter calculated?

A discharge coefficient is used to account for inaccuracies resulting from assuming plug flow and neglecting friction in the Bernoulli equation.


Why is coefficient of discharge of venturi meter is more than coefficient of discharge of orifice meter?

In Venturi meter losses are less so coefficient of discharge is higher whereas in orifice meter due to no convergent and divergent cones there are more losses and hence its coefficient of discharge is less.In venturi meter losses are low due to steamline shape of the diffuser and the pressure gradient is not abrupt as in case of orifice meter.

Is coefficient of discharge constant?

No coefficient of discharge is not constant. It is a function of many parameters like :The ratio of the length of the orifice to diameter of orificeReynolds numberflow condition-whether it is increasing or decreasingPressure at the exit of the orifice (back pressure)Orifice entry condition- like smooth entry, sharp edged entry etc.


Coefficient of discharge is a dimensionless parameter?

It is a dimensionless parameter since its just a ratio between two quantities of same unit.
