Answer / vinodh kumar j

hai dudes,

According to Bernelle's equation in an orifice meter there
is relationship between velocity & pressure.
If incoming velocity is more then the fluid passing the
orifice will have less velocity but more pressure.
there is no relationship with temp.

According to Bernelle's equation

P1 + 0.5 DV1^2 = P2 + 0.5 DV2^2
P - PRESSURE
D - DENSITY
V - VELOCITY
