For steady incompressible ideal flow along a streamline, which statements are correct?

Select all that apply

• Option A

  A decrease in area generally increases speed

• Option B

  In a horizontal pipe, higher speed corresponds to lower static pressure

• Option C

  Bernoulli's constant includes pressure, kinetic-energy density and gravitational-potential-energy density

• Option D

  Bernoulli's equation requires the speed to be the same at all points
