In the derivation of the Bernoulli equation we obtained the following differential equation for the acceleration along a streamline. If the flow is upward, the angle = 90o; if the flow is downward, the angle = –90o. For an upward flow, then, the required pressure gradient is found to be

From the Bernoulli equation we can obtain the following relationship. where point 1 is on a horizontal line in the jet away from the stagnation point and point 2 is the stagnation point. The stagnation pressure, , will be measured using a pressure transducer. Equation requires the assumption that the streamlines are straight and parallel ...

The Bernoulli equation with no effect of elevation gives us. Substituting data for the velocities and the definition of the reference gage pressure as p1 = 0 gives. p3 = –70.6 lbf/ft2. Applying the Bernoulli equation along a stagnation streamline to point 2, where V2= 0 gives. p2 = 88.0 lbf/ft2

Bernoulli’s Equation. An increase in the speed of a fluid occurs simultaneously with a decrease in pressure or a decrease in the fluid’s potential energy. The left side of the equation represents point 1, with the right side representing point 2 (before and after) P1 + 1/2pv21 + pgh1 = P2 +1/2pv22 + pgh2

Bernoulli’s Equation Part II 1 Water flows through the pipe contraction shown in the figure at the right. For the given 0.2-m difference in manometer level, determine the flow rate as a function of the diameter of the small pipe, D. (Problem and figure 3.30 from Munson et al., Fluid Mechanics text.)

The Bernoulli equation is actually a first integral of Newton's second law along a streamline. This general integration was possible because, in the absence of viscous effects, the fluid system considered was a conservative system. The total energy of the system remains constant. If viscous effects are important the system is nonconservative ...

If Bernoulli’s equation applies along the whole length of the streamline from the airbox, then P should be the same everywhere as the initial total pressure Po. The value of Po may be found easily from a pressure tapping in the wall, since the air velocity in the box is so slight as to make the difference between total pressure and static ...
The Bernoulli Differential Equation - MATH
Water is flowing in a fire hose with a velocity of 1.0 m/s and a pressure of 200000 Pa. At the nozzle the pressure decreases to atmospheric pressure (101300 Pa), there is no change in height. Use the Bernoulli equation to calculate the velocity of the water exiting the nozzle. (Hint: The density of water is 1000 kg/m3 and gravity

Write Bernoulli’s equation along the stagnation streamline from A to B. Take the datum for elevations at the water surface at A. Then zB is the amount of rise in the water surface. Solve Bernoulli’s equation for zB. In order to get this solution, you must get appropriate values for pA, pB, and VB.
