Converting Wind Pressure to km/h for Aluminium Openings | 2400 Pa Resistance

[nicolasmarie]

Hi,

I want to express a wind pressure of 2400 Pascals in terms of km/h (speed) ?

The context here is Aluminium Openings having to resist such pressure.

Thanks in advance,

Regards,

Nicolas.

u can use bernollis equation assuming it a ideal fluid and perfect horizontal flow
(pressure/density)=(((veocity)^2)/2)

Thank you for your reply.

I have a pressure of 2400 Pascal.

Reworking your formula from the standpoint of pressure and using a density of 1.2923 (kg/cu m), I am getting as answer: 60 for velocity. (I think it is 60 m/s or 216 km/h).

I have used an online converter called Cactus 2000 and got 60.945 m/s or 219.4 km/h.

Is there a reason for the discrepancy 216 km/h and 219.4 km/h?

Am I using the right density of 1.2923 kg/cm?

Thanks,

Regards,

Nicolas

I have just check the excel sheet anew, there is no discrepancy. The wind speed using equation and online converter is 219.4 km/h using a wind density of 1.2923 kg/cu m.
