Hi Everyone,
This is a real simple question, but I should make sure I have this right. In the following formula, is the value of P in watts?

P = 1/2 Aρv3

I'm assuming that this is in watts, but you know what they say about assuming. Thanks in advance for your help!
Cheers,
Rick

Assuming ρ is in [kg/m3] and v is in [m/s] and A is in [m2], then yes P is in watts.

Hello MrMatt,
Thank you very much, I was using Slugs for ρ and A was equal to FT2, but I can convert them to metrics. Glad I double checked!
Cheers,
Rick
