In the following fig. is shown the flow of liquid through a horizontal pipe. Three tubes $A, B$ and $ C$ are connected to the pipe. The radii of the tubes $A, B $ and $C$ at the junction are respectively $ 2 cm, 1 cm$ and $2 cm.$ It can be said that the

(d)As cross-section areas of both the tubes $ A $ and $ C$ are same and tube is horizontal. Hence according to equation of continuity ${v_A} = {v_C}$ and therefore according to Bernoulli's theorem ${P_A} = {P_C}$i.e. height of liquid is same in both the tubes $ A$ and $ C.$
