Hi, the equation I have is for gas flow in a pipe 'Q' being the flow rate in m³/s. I am having great difficulty in transposing to get D as the subject (D being the internal pipe diameter), can anyone help. The Number pd is the pressure drop Pa/m
q= -2.695*sqrt(pd)*(D)^2.5*log(((4.05*10^-7)/D)+(2.3*10^-5)/sqrt(pd)/D^1.5))
This equation is correct for flow 'Q' I would just like to make D the subject.
I am just rubbish at transposing. Can anyone help.
Thank you
