Transcribed Image Text:**Exercise 5.42: Bow Thruster Application in Marine Engineering**
In this exercise, we explore an application of bow thrusters, a key innovation in marine engineering. Refer to the "Fluids in the News" article on Bow Thrusters (Section 5.2.2) for more background information.
**Scenario:**
The bow thruster on the boat in Figure P5.42 is designed to aid in maneuvering. The device operates by generating a 1-meter diameter jet of water with a velocity of 10 meters per second. Your task is to determine the force exerted by the thruster.
**Assumptions:**
- The inlet and outlet pressures are considered to be zero.
- The momentum of water entering the thruster can be disregarded.
**Diagram Explanation:**
- The diagram depicts a top-down view of a boat equipped with a bow thruster located near the front section.
- Water is expelled perpendicularly from the side at a velocity of 10 m/s and a diameter of 1 meter.
- The force impacts the direction and speed of the boat's turn.
Calculate the force by considering the momentum change of the water jet based on the given parameters, neglecting any potential energy losses or inefficiencies in the system.
