Can someone explain something to me:(adsbygoogle = window.adsbygoogle || []).push({});

I believe when throttling h1=h2.

When calculating enthalpy drop across a FIXED converging nozzle then kinetic energy is caluclated using the following formula:

h1-h2 = v2^2/2 - v1^2/2

If the nozzle is converging then there will be an increase in kinetic energy, but, if assuming the nozzle is throttling with a respective pressure drop then how can h1=h2 as this would mean v1=v2?

Thanks
