Applied Fluid Mechanics

A fluid is a substance that is continuously deformed by the application of shear stress. The rate of deformation of a fluid depends on its viscosity. The fluid tries to flow when it interacts with some other system.

**Bow Thrusters and Their Working Principle**

The bow thruster on the boat, illustrated in the diagram, is a mechanism used to change the direction of the boat. This thruster produces a jet of water with a diameter of 0.91 meters, moving at a velocity of 5.2 meters per second. The task is to determine the force generated by this thruster. It is assumed that the inlet and outlet pressures are zero, and the momentum of the water entering the thruster is negligible.

**Diagram Explanation:**

- The diagram shows a top view of a boat with the bow thruster located at the front (bow) of the boat.
- A circular region indicates where water is expelled, marked with a diameter \( D = 0.91 \, \text{m} \).
- The jet of water is shown with an arrow pointing outward to represent its velocity of \( v = 5.2 \, \text{m/s} \).
- Force \( F_y \) is to be calculated and is expressed in kilonewtons (kN).
