Yes the relative velocity of jet will be V-u Where, V= jet velocity u= plate velocity But after striking with plate the exit velocity renains same as V-u. So there is no energy balance.

Nothing such reaction force exists.

What if the plate is not fixed but moving like a blade of a turbine. The whole principle is based on impulse momentum. I read that the plate change the direction of jet hence the momenum of jet also changes which in turn applies the force. Force= change in momentum = mass flow rate...

Consider a case- Force excerted on a stationary flat plate held normal to the jet. The Jet strikes on plate (see fig.) Which is smooth hence the exit velococity of jet = entering velocity of jet. According to theory. The fore is applied on plate due to change in momentum of jet. But my doubt...

As we all know that in atmospheric pressure (1 Bar) saturation temperature of water is 100 deg C. And the air contains mixture of dry air and water vapour. My doubt is here that the water needs 100 deg Celsius to change from liquid to vapour state then how can a normal room temperature air...
