Final answer:
The question misaligns information about a C-300/C-301 Ground-Servicing Unit with a fluid mechanics problem, but it essentially deals with changes in pressure in a hose due to alterations in height and diameter, using principles from Bernoulli's equation and the continuity equation.
Step-by-step explanation:
The question seems to be related to the properties of a fluid in a hose which is part of the C-300/C-301 Ground-Servicing Unit, a piece of engineering equipment. However, the information provided about a 3.00 cm inside diameter hose that rises 2.50 m above the pump and then goes over a foundation wall seems to be part of a different problem, likely related to fluid mechanics and pressure changes within a hose due to height changes and diameter variations. This fluid mechanics concept can be explained through the principle of conservation of energy, typically represented in the form of Bernoulli's equation.
According to Bernoulli's theorem, the pressure in a fluid decreases as the height increases and vice versa when the height decreases, considering no energy losses. In the case where the hose widens, continuity equation suggests the velocity of the fluid will decrease, and typically the pressure will increase assuming incompressible flow.
In summary, to determine the pressure at various points in the hose system, we use Bernoulli's equation, which relates the pressure, potential energy due to height, and the kinetic energy due to fluid flow. So for part (a), when the hose is at 2.50 m above the pump, the pressure can be calculated considering the elevation head and the hose's initial pressure. For part (b), when the hose goes over the wall and widens, the pressure changes can be found by considering the decrease in height (potential energy) and increase in cross-sectional area.
