Homework Statement
Work out the mass flow rate of Nitrogen traveling through a at 0.3m^3/s if the pressure is 1 bar and the temperature is 18°C and the ideal gas constant is 8314 J/Kg K
Homework Equations
m=ρ*V*A
m = mass flow rate
ρ= density
V = velocity
A = flow area
PV = nRT
where
P = pressure
V = volume
n = number of moles of gas
R = gas constant
T = absolute temperature
The Attempt at a Solution
I'm going round and round in a circle with it, the formula is simple enough and I know how to re-arrange it to get density but I need to work out the volume which is:
V = nRT/P
in order to do this I need to find the number of moles which is:
mass of the gas/ molecular mass
how do I work out the mass of the gas?
and how do I work out the flow area when there isn't one provided?
Thanks
