npleu, wilal is the hew net force on the dam? Problem #2: Fire hoses used in major structural fires have an inside diameter of 3.8 cm. Suppose such a hose carries a flow of 30.0 L/s. The hose rises 10.0 m along a ladder to a nozzle having an inside diameter of 2.4 cm. 10 m a. What is the velocity of the water in the hose? b. What is the velocity of the water in the nozzle? C. Assuming a gauge pressure at the nozzle of 0 Pa (atmospheric pressure) what is the gauge pressure of the water in the hose?
Fluid Pressure
The term fluid pressure is coined as, the measurement of the force per unit area of a given surface of a closed container. It is a branch of physics that helps to study the properties of fluid under various conditions of force.
Gauge Pressure
Pressure is the physical force acting per unit area on a body; the applied force is perpendicular to the surface of the object per unit area. The air around us at sea level exerts a pressure (atmospheric pressure) of about 14.7 psi but this doesn’t seem to bother anyone as the bodily fluids are constantly pushing outwards with the same force but if one swims down into the ocean a few feet below the surface one can notice the difference, there is increased pressure on the eardrum, this is due to an increase in hydrostatic pressure.
