Water flows through a circular pipe with a constant radius of 10cm. The speed and pressure at point A is 4m/s and 250,000Pa respectively. a. What is the speed of the fluid at Point B? b. What is the pressure at point B is 10m higher than point 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.
- Water flows through a circular pipe with a constant radius of 10cm. The speed and pressure at point A is 4m/s and 250,000Pa respectively.
a. What is the speed of the fluid at Point B?
b. What is the pressure at point B is 10m higher than point A - A sealed storage tank contains water to a height of 25 m. The air above the water inside the tank has a gauge pressure of 4.5 atm. How fast will water flow out the hole that is located at the bottom of the tank?
