(a)What is the pressure drop (in N/m2) due to the Bernoulli effect as water goes into a 3.50 cm diameter nozzle from a 9.10 cm diameter fire hose while carrying a flow of 41.0 L/s? Answer ___________ N/m2 (Enter a Number) (b) To what maximum height (in m) above the nozzle can this water rise? (The actual height will be significantly smaller due to air resistance.) Answer ____________ m (Enter a Number)
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.
