i mean that the case of water boiling at "atmospheric pressure and 100°" is same as that of water boiling at "room temperature below atmospheric pressure".
∴, since you said boiling below atmospheric pressure causes decrease of water temperature, the same effect i.e. lowering of temperature...
yes but the same energy is given by lowering the pressure, lowering the pressure is same as increasing the temperature of the water to boiling point, and if temp of water decreases due to lowering of pressure then temp of water should also drop on increasing temperature at atmospheric...
assuming water at atmospheric conditions, now if the pressure is reduced, at some lower point of pressure, water starts to boil.at this point, will the temp of water change and why?
i am talking about the velocity profile of the liquid, i know that from the equation it comes out to be a parabola equation, but what is its meaning, i mean why is it that velocity is maximum at the centre of the pipe and zero, at the corners?
when any liquid flows through a pipe, the curve made by it is paraboloid, what is the reason for this shape. also the equation tells that it is independent of the liquid flowing through the pipe
