Question
A large open tank has two holes in the wall. One is a square hole of side L at a depth y from the top and the other is a circular hole of radius if at a depth 5y from the top. When the tank is completely filled with water the quantities of water flowing out per second from both the holes are the same. Then R is equal to

Question
An incompressible liquid flows through a horizontal tube as shown in trite following fig. Then the velocity v of the fluid is
Flow of Horizontal Fluid - the Velocity v of the Fluid
In above figure we show that in starting fluid flow with 3 m/s and then it divided in two way with velocity of 1.5 m/s
