Water flows through a Venturi meter, as shown in the figure. The pressures of the water at locations a and b in the pipe support columns of water that differ in height by L = 20 in. The atmospheric pressure is 14.7 lbf/in2, the specific volume of water is 0.01604 ft³/lb, and the acceleration of gravity is g = 32.0 ft/s². Step 1 Patm = 14.7 lbf/in.² g= 32.0 ft/s² Determine the difference in pressure between points a and b, in lbf/in². Does the pressure increase or decrease from point a to point b? X Your answer is incorrect. Water v=0.01604 ft³/lb L Determine the difference in pressure between points a and b, in lbf/in². Pb-Pa = i 23.09 lbf/in²
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.
