Pressure increase as area increase and velocity decrease so the correct anwer is B)increase
Option B is the correct answer, ie the pressure should increase in the divergent section of ventury meter
increases
As per Bernoulli's equation as area increases velocity decreases and pressure increases so the right entries option C pressure decreases
B. Increases
And according to continuity equation we know velocity will decrease with increase in area in diverging portion so as the kinetic energy increase and according to bernoulli eq pressure must decrease otherwise law of conservation of energy will be violent.
It should be increases as per Bernoulli's equation
Option B is the correct answer, ie the pressure should increase in the divergent section of ventury meter
i hv some doubt. as per bernaullies theorem pressure should increase through divergent portion @ the expense of K.E .
