airflow velocity

[ozzworth]

Designing a heating core into a 1.5 inch tube to raise an ambient temp. of 40 degrees to 60 degrees. Have a flow velocity of 98 CFM produced by a squirrel-cage fan, but have no way of finding the PRESSURE of the air-flow.

I suspect it's less than 15 psi... Any assistance would be most helpfull...

Are you wanting to measure the static pressure in the pipe or the&nbsp;&nbsp;dynamic pressure of the free air flow from the fan?<br><br> <p>Nigel Waterhouse<br><a href=mailto:n_a_waterhouse@hotmail.com>n_a_waterhouse@hotmail.com</a><br><a href= > </a><br>A licensed aircraft mechanic and graduate engineer.
