qqp question1: In a water flowing pipeline, if the diameter of a pipe is reduced, the pressure in the line will increase. Bernoulli's theorem says that there should be a reduction in pressure when the area is reduced. What is the justification for this? question2: Boiling water, under a pressure of 1.2 bar, is reduced to a pressure of 0.5 bar. How much steam forms per kg of water?
