What is the difference between the pressure at the two sections? Water flows thiough a horizonial pipe at o velociry of 50 f per secon d. Owing to the pipe gradually expanding to Targer rize the velociy decreases to 35 fy per second, what i the differente between the prewures at two points, one in each size of pipe ? Given : VA = 50fps Ve -35 fps 1,165.15 psf 1,021.96 psf 1,421.88 psf 1,345.11 psf 1,236.75 psf
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.
