roblems 1. 600 80 cm tall cylinder is filled with water (Pwater = 1000 kg/m³) and oil (Poil kg/m²) and is capped on the bottom so no fluid is flowing. It contains equal amounts of the two fluids by weight. What is the pressure at the bottom of the cup? == 2. An above ground pool is being drained using a single hose as shown in the picture below. The hose has a circular cross-section with a diameter of 3.5 cm and runs from the bottom of the pool, up over the side of the pool, and extends 1.0 m below the pool where water is leaving the hose. The pool wall is 1.5 m tall and the pool is currently filled to a depth of 1.25 m. Assume the pool is much larger than the hose so that the depth of the pool changes very slowly. (a) What is the speed of the water leaving the hose? (b) What is the gauge pressure in the hose at point A? A
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.
