Answer 1

False. It's Pascal's Law that states that a pressure applied to a confined fluid is transmitted undiminished through that fluid.

Bernoullis's Law applies to a flowing fluid along streamlines as in a pipe and says that the sum of the pressure, the kinetic energy per unit volume and the potential energy per unit volume at one point is the same at any other point along that stream line for a nonviscous incompressible fluid in steady flow.

Stated with an equation it is\[P _{1} +\frac{ 1 }{2 }\rho v _{1} ^{2} +\rho gh _{1} = P _{2} +\frac{ 1 }{2 }\rho v _{2} ^{2} +\rho gh _{2} \] where rho is the density of the fluid, h is the height above a reference point for potential energy and v is the velocity at that point. The velocity is related to the flow which is constant throughout the pipe for a non compressible fluid.

Flow at (a) = velocity at (a) x cross-sectional area at (a) \[flow _{a} = v _{a}* A _{a}\]

where flow is measured in cubic meters/sec , area in sq meters and velocity in meters/sec..

Hope this helps.
