Part (b) The hose then goes over the foundation wall, losing 0.65 m in height, and widens to 5.7 cm in diameter. What is the pressure now, in pascals? You may neglect frictional losses. Numeric A numeric value is expected and not an expression. P3 =
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.
9.10 please answer part b, other parts are answered. The hints for part b are: (1) Bernoulli's equation can be used to relate the characteristics of a fluid flow at it's initial and final points. (2) Use equation of continuity to find velocity of water in different parts of a pipe. The answers I have gotten are .9339, 169000, 1.56, and 156000 but they are wrong
