In PV table, in some cases max velocity and max.pr not mentioned? What it implies?

[@engineeringmaterials-tribo5142]

The table was taken from a book. I am sorry those data were not available. If you are doing your own research then you need to ensure to measure both velocity and pressure. Thanks for asking 👍

@@engineeringmaterials-tribo5142 Thank you for reply, if we are able to construct PV diagram from experiment results of pin on disc?
