Nusselt number (NN) is given by
A. $${{\text{N}}_{\text{N}}} = \frac{{{\text{h}}l}}{{\text{k}}}$$
B. $${{\text{N}}_{\text{N}}} = \frac{{\mu {{\text{c}}_{\text{p}}}}}{{\text{k}}}$$
C. $${{\text{N}}_{\text{N}}} = \frac{{\rho {\text{V}}l}}{\mu }$$
D. $${{\text{N}}_{\text{N}}} = \frac{{{{\text{V}}^2}}}{{{\text{t}}{{\text{c}}_{\text{p}}}}}$$
In case of sensible heating of air, the coil efficiency is given by (where B.P.F. = Bypass factor)
A. B.P.F. - 1
B. 1 - B.P.F.
C. $$\frac{1}{{{\text{B}}{\text{.P}}{\text{.F}}{\text{.}}}}$$
D. 1 + B.P.F.
The undesirable property of a refrigerant is
A. Non-toxic
B. Non-flammable
C. Non-explosive
D. High boiling point
The desirable property of a refrigerant is
A. Low boiling point
B. High critical temperature
C. High latent heat of vaporisation
D. All of these
In evaporetor at the when all liquid vaporied, C is appropriate answer
If refrigerant is very wet vapour before entering the compressor then due to moisture present in the refrigerant there will be wear and tear of the moving parts inside the compressor due to sudden expansion of heat inside the compressor.
Hence, option D is incorrect.
Answer: Option C.
Option D is not correct because of very wet vapour getting after throttling or expansion
Option c is correct condition refrigerant is very wet after passing through the expansion valve and before entering the compressor dry saturated vapour
correct answer is C option. Refrigerant is in dry saturated or even superheated before entering the compressor
Ya options C is the right ans .
If u don't know about it then how u can ans strongly.
... The refrigerant is become wet vapour at the stage of entering to evaporator
All option are wrong.... The refrigerant is become wet vapour at the stage of entering to evaporator
Option (C) is right.
Before entering the compressor it becomes Dry saturated vapour.
Option C is the right answer
