Hi,
Can someone please tell me if pressure is a state variable in a momentum equation for a fluid, considering that the equation is mechanical and does not have any temperature terms.
Thanks!

You'll have to provide the equation or chart to receive a more specific response, but as a general rule pressure is a fundamental property that can be used to fix a fluid's state.
