Assertion (A): After the fluid downstream of the orifice plate has re-established, it will return to the same pressure that it had upstream of the orifice plate.
Reason (R): According to Bernoulli’s theorem with usual assumptions, for flow between two points, the sum of kinetic, potential and pressure energies remain constant.
(A) Both A and R are individually true and R is the correct explanation of A
(B) Both A and R are individually true but R is NOT the correct explanation of A
(C) A is true but R is false
(D) A is false but R is true
