Question
According to Bernoulli's equation, if an incompressible fluid passes through a cylindrical set of pipes such that the fluid velocity in the narrower of the two is 2 times that of the wider section, then
the change in pressure decreases by a factor of 2.
the change in pressure increases by a factor of 2.
the change in pressure increases by a factor of 3.
the change in pressure decreases by a factor of 3.
there is no change in pressue.
the change in pressure decreases by a factor of 2.
the change in pressure increases by a factor of 2.
the change in pressure increases by a factor of 3.
the change in pressure decreases by a factor of 3.
there is no change in pressue.
Explanation / Answer
According to Bernoulli's theory, in the case of an incompressible fluid, the total pressure of the fluid through-out the flow remains always constant.
Hence following this, the last option, 'there is no change in pressure' is the correct answer.
