Water flows through a pipe as shown in the figure. The pressure at points 1 and 2 respectively is 1.90 x 105 Pa and 1.20 x 105 Pa. The radius of the pipe at points 1 and 2 respectively is 3.90 cm and 1.10 cm. If the vertical distance between points 1 and 2 is 2.75 m, determine the following. (a) speed of flow at point 1 084 x If you use points 1 and 2 to write Bernoulli's Equation and the equation of continuity, you will have two equations and two unknowns. See if you can manipulate these to obtain the speed of the fluid flow at point 1. m/s (b).speed of flow at point 2 10.66 Enter a number. know the speed of the fluid flow at point 1 from part (a), see if you can use i either bulli's Equation or the equation of continuity to obtain the speed of fluid flow at point 2, m/s (c) volume flow rate of the fluid through the pipe 0.004011 Knowing the radius of the pipe and the speed of the fluid flow at two different points, see if you can determine the volume flow rate at these two points. m³/s Additional Materials Reading
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.
