## Main Question or Discussion Point

When designing an orifice plate to reduce the pressure of a constant flowing liquid, is it best to have one large hole in the center or multiple smaller holes?

One example: Pipe diameter = 10 inches, Flow = 2800 gpm water, pressure drop = 150 psi, temperature = 115 F. The hole diameter needs to be about 6 inches.

If many smaller holes are better, how are they sized? Do you have there cross-sectional areas add up to the cross-sectional area of the 6 in hole?

Thank you.
