 October 22, 2004, 05:37 static pressure from mass flow rate #1 SAM Guest   Posts: n/a it is stated in fluent user guide that for target mass flow rate it finds the mean static pressure and then finds mass flow rate and then subtract from target mass flow rate and finds again static pressure i want to know by whcih equation it finds that static pressure , coz we dont know the mach number , total pressure at outlet etc regards

And it is almost the same for method 1 since mass-flow rate is known for the previous iteration
