General Information<br />

ORIFICE PRESSURE DROP DATA<br />

These charts are based on<br />

the formula:<br />

= orifice coefficient<br />

P = pressure drop N/m2 Where:<br />

Q = Flow m3 Q = a A 2AP<br />

/sec.<br />

A = orifice dia. cm2 r<br />

a<br />

D<br />

= density Ns2 /m4 r<br />

No allowance has been made for viscosity effects, or regain of pressure downstream.<br />
