Hi,
imagine we have a vertical pipe, we have also measured the temperature and pressure above the pipe and at the bottom of the pipe. sometimes the temperature at the bottom is higher than the upper part and sometimes the pressure is. I was wondering how can I formulate these effects on air velocity either at the upper part or at the bottom?
Thanks
Hi,
thanks. I know that but I need the formula.
it should be:
Cv dT+ dP/density+ mv2/2=0
but I am nit sure if it is right….
