Pressure increases with decrease in area and so does velocity, then why is it said that pressure decreases with increase in velocity?

Expert Answer:

According to Bernoulli’s theorem,

P + ½ ρv 2 + ρgh = constant

Where,

P = pressure

ρ = density

v = velocity

h = height from the ground

If the ‘h’ is constant we observe that increase in pressure P will decrease v and decrease in P will increase  to keep the equation constant.
