Theodore L. Bergman, Adrienne S. Lavine, Frank P. Incropera. WebHigh pressure and energy recovery makes the venturi meter suitable where only small pressure heads are available. A discharge coefficient c d = 0.975 can be indicated as standard, but the value varies noticeably at low values of the Reynolds number. The pressure recovery is much better for the venturi meter than for the orifice plate. four season hotel in mexico city
