The pressure and velocity at the throat of a Venturi tube, measuring the flow of a liquid, are related to the upstream pressure and velocity, respectively, as follows:
(A) Pressure is lower but velocity is higher
(B) Pressure is higher but velocity is lower
(C) Both pressure and velocity are lower
(D) Pressure and velocity are identical
(A) Pressure is lower but velocity is higher
(B) Pressure is higher but velocity is lower
(C) Both pressure and velocity are lower
(D) Pressure and velocity are identical
