Question:-
Match List-I with List-II ans select the correct
List- I
A. Reynolds Number
B. Pradtl number
C. Nusset number
D. Mach number
List-_II
1. Film coefficient, Pipe diameter, thermal conductivity
2. Flow velocity, acoustic velocity
3. Heat capacity dynamic viscosity, thermal conductivity
4. Flow velocity, pipe diameter, kinematic viscosity
Option (A)


A B C D
4 1 3 2

Option (B)


A B C D
4 3 1 2

Option(C)


A B C D
2 3 1 4

Option(D)


A B C D
2 1 3 4

Correct Option:
(B)
Question Solution:
Reynolds number = (V.D/v)
V= velocity
V = kinematic viscosity = (m/r)
= (dynamic viscosity / density of fluid)
Prandtl No = (mcp/k)
Nusselt No = (hD/k)
Mach No = (V/C) = (flow velocity / acoustic velocity)
