... Data:-
$u=1.5 poise=0.15 N-s/m^2$
$S_{oil}=0.9,L=20m$
$D=3cm=3\times 10^{-2}m$
$P_A=200kPa=200\times 10^3N/m^2$
$P_B=500kPa=500\times 10^3N/m^2$
To find:-
(a) Direction of flow=?
(b)Rate of flow=?
Solution:-
(a)Direction of flow:
Total energy at point A
$T.E_A=\frac{P_A}{S_{oil}.9}+Z_A$

... Mach Number:-
It is defined as the ratio of actual velocity v to the sonic velocity c
$\therefore M=\frac{v}{c}$
when
$M\gt 1$.......Flow is supersonic
$M\lt 1$.......Flow is subsonic
$M=1$.......Flow is sonic
Stagnation pressure:-
The stagnation pressure $P_0$ is related to mach number and ...

... Air at an absolute pressure 60.0 kPa and $27^\circ$ enters a passage at 486 m/s. The cross sectional area at the entrance is 0.02 $m^2$. At section 2, further downstream, the pressure is 78.8 kPa(abs). Assuming isotropic flow. Calculate the mach no. at section 2. Also identify the type of nozzle. ...
