Answer :
Final answer:
The hosel line on the P-25 is 30 ft in length with a flow rate of 25 GPM, determined using the fluid speed formula. Therefore the correct answer is: a)
Explanation:
Fluid dynamics is the branch of physics that deals with the study of fluids in motion, including liquids and gases. It encompasses a wide range of phenomena, from the flow of water in rivers to the aerodynamics of airplanes. Here are some key concepts and areas within fluid dynamics:
Fluid Properties: Fluids are substances that can flow and take the shape of their container. They exhibit properties such as density, viscosity, pressure, and temperature.
Continuity Equation: This equation states that the mass flow rate of a fluid remains constant along a streamline. It is based on the principle of conservation of mass.
Bernoulli's Principle: Bernoulli's principle describes the relationship between fluid speed and pressure in a moving fluid. It states that an increase in the speed of a fluid occurs simultaneously with a decrease in pressure or potential energy.
The hosel line on the P-25 is 30 ft and the flow rate is 25 GPM.
This can be determined using the formula:
Flow rate = Cross-sectional area x fluid speed. Substituting the values given, 9.00 cm diameter, and 80.0 L/s, we can calculate the speed and convert it to GPM.
Therefore, the correct answer is a) 30 ft, 25 GPM.
