static pressure from mass flow rate
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 
Re: static pressure from mass flow rate
Quote from method 2: Second Step: use the required mass flow rate (the target mass flow rate), the current computed mass flow rate, and mean static pressure in Bernoulli's equation  to obtain a new mean static pressure value, applying underrelaxation to keep the solution stable.
And it is almost the same for method 1 since massflow rate is known for the previous iteration 
Re: static pressure from mass flow rate
but bernouli equaton, where does it contain mass flow rate term
confused plz help 
Re: static pressure from mass flow rate
G {massflow rate }= B {constant, properties}* P_tot * function (P_tot, P_stat) * Area / sqrt ( R_gas * T_tot)

Re: static pressure from mass flow rate
thanks i will try it and let u know
regards 
Re: static pressure from mass flow rate
wat is B and how we calculate p total
can u explain this formula or give book name i would be thanful to u
