Partial pressure calculation

Partial pressure calculation

(OP)
Hi!

I a have hydrocarbon gas mixture whose total pressure is Pt(measured by gage)over 40Barg. Is it correct for  computing the partial pressure of components by using this formula: Pi(partial pressure of one component), Yi(molar fraction)

Pi= Yi * Pt

Thanks  

RE: Partial pressure calculation
