Airflow and Preassure HW: Find Flow for Engine Needing 1m3/min

[hovor]

Homework Statement

Engine needs airflow of 1 m3/min (std. p=101.325kPa, T=293.15K) it is suplied by machine working at p=700kPa.

Homework Equations

How big flow is requied from the machine to supply engine with air?

The Attempt at a Solution

Tryed using ideal gas law pV=nRT
1) I found out n, using n=(pV)/(RT)=(101,325*1)/(8,314*293,15)=0,04157
2)I used 2nd preasure to add to to eq. V2=(nRT)/p=(0,04157*8,314*293,15)/700=0,14475m3/min

Have no way to check if that is correct or not.

You must show some attempt. Tell us what you know. This must be relevant to something you are learning in a textbook.

hope that will do, I honestly don't know tho
