ASME states that you should not use an enlarger before a PSV on a vessel. Can someone give me an explanation to why this is?
 
Besides a flow nozzle being a better descriptive term for the physical and mathematical model of a PSV, a converging flow nozzle is also less susceptible to upstream flow disturbances than an orifice would be, that's my opinion.

Good luck,
