Very much appreciated (for double checking my work and for the insight into KSC practices). I assumed a Cd of 1 as a "worst case" maximum flow rate, but I suppose that would be a good assumption to state in the problem. Thanks again.

Greg, This post has been answered on a different thread (https://www.physicsforums.com/threads/how-do-i-calculate-the-pressure-drop-of-air-across-an-orifice.772771/#post-4874752), and therefore can be deleted. Thanks! -Mike

Guys, here is my final result. I ended up using a 0.070" orifice to reduce the flow rate to meet the specs in the muffler I was looking into purchasing. Thanks again for your help

How could one calculate the effects of any flow-induced vibrations?

Thanks for the responses, Q_Goest and jack action. You both understood and answered my question. Jack- you did not misunderstand my question, on the contrary I misunderstood your response (I apologize!). I had not seen the pressure-drop calculator in my searches, so that was very helpful. Q...

Thanks for the input

My apologies. As I stated above, the maximum internal pressure of the pipeline under flow will be 120 psig.

The pipe is located outside, so just atmospheric conditions. The internal flow rate of the water is about 400 gpm at a discharge pressure of up to 120 psig.

Thanks for the input. I expect 40F and it is a 304SS. Is there an easy way to look up ASME sections, or do you recommend being a member to acquire access to the full database of codes, etc.? And yes, good call on the flow-induced vibrations. I'll make sure to be conservative in my approach.

Gee I never would have thought to use the internet to search for the answer... Oh no wait- that's the only thing I did! And no that does not answer my question. But thanks anyway.

I'd like to add a temperature probe to a 4" water pipe downstream of a centrifugal fill pump, but I am afraid of the probe shearing from being subjected to a constant force from the upstream pump (which pumps at about 400 gal/min). Naturally, my thought was to use the drag force equation, but I...

I would like to install a vent stone on a 3/4" vent line. The line vents upwards of 1500 psig of stored gasous nitrogen in under 1 second. The vent stones are only rated for 300 psig, so I'd like to add an orifice just upstream to limit the exit flow rate to a point where it can handle the...

Thanks for the response. Unfortunately, my question was how to correctly determine the pressure drop across the orifice assuming I am venting to atmosphere and I have 1600 psig upstream. For example, if I WANT the pressure to drop from 1600 to 200, then how do I size my orifice accordingly...

I am trying to size an orifice to place on an outlet of an air vent line. The reason for this is that I am installing a noise suppressing muffler, but it is only rated for 300 psig. Since I am venting a line that will be pressurized to 1600 psig, I'd like an orifice restrictor in order to...

I have a magnetic-mount heater (300 to 400 degF output) that I want to put on a pump that I wish to protect from freezing weather. However, considering that there are various components on the pump that are only rated up to 185 and 200 degF, I'd like to add some sort of temperature control...
