Which of the following statements is false?

A) The lift force (per unit length) on a body depends on the density of the fluid

B) For laminar flow through a pipe, the loss of head is directly proportional to velocity as well as viscosity of fluid

C) A hydraulic jump occurs when a supercritical flow comes across sub critical flow

D) At the stall point for the airfoil, the lift is minimum and the drag decreases sharply beyond it.
