Answer First, we use the continuity equation to relate the two velocities. The two areas are related by A1 = 4A2 (note that it's 4, not 2: if the radius doubles, the area quadruples.) Thus the continuity equation says that v1A1 = v2A2 so that v2 = 4v1 (the uid in the larger pipe ows slower, and with greater pressure). Now using the above equation gives P1 P2 = 1 2 (v2 2 v2 1) 100 Pa = 1 2 (1000 kg=m3)(16v2 1 v2 1) Solving for v1 gives v1 = s 100 (500)(15) m=s = :12m=s To get the full Bernoulli's equation, we just need to include gravity like we did before. Now let's consider a pipe which goes up and downhill. Then we need to do work to get the water to go uphill as well, from y1 to y2. The potential energy is as always mgh. We then have (P1 P2)V = 1 2 mv2 2 1 2 mv2 1 + mg(y2 y1) 3 Rearraging again gives Bernoulli's equation: P1 + 1 2 v2 1 + gy1 = P2 + 1 2 v2 2 + gy2 If you set the velocities equal to zero like we were doing last time, then this equation reduces to our earlier one. There are many consequences of Bernoulli's equation. In fact, Bernoulli's equation also applies to air. It's why planes y, and curve balls curve. The basic idea is that when air is moving faster, its pressure is lower. Thus if you manage to have an object like a Baseball or a plane wing with dierent pressures on dierent sides, the object will feel a net force. A spinning baseball drags some of the air with it. This means on opposite sides, the air is moving at dierent speeds. This results in a change in pressure, and makes the ball move sideways. The shape of a plane wing causes the air rushing past to go faster on top. This lowers the pressure and hence causes the wing to lift up. 4
Tangent continuity: No sharp angles. Curvature continuity: No sharp radius changes.
An equation is a mathematical that asserts theequality of two expressions. An inequality is a relation that holds between two values when they are different.
An equation is a ploblem with no answer and an expression is a problem with an answer so you'll get different answers with an equation and an expression.
There is no such thing as a quadric equation. The nearest word is quartic which is an equation involving the fourth power of the independent variable. It is unlikely that you will have come across that. It is possible that you might be wanting to refer to a quadratic equation, which is the equation of a parabola. That being the case, they two represent the same thing.

The continuity equation states that the mass flow rate is constant in an incompressible fluid, while Bernoulli's equation relates the pressure, velocity, and elevation of a fluid in steady flow. Together, they help describe the relationship between fluid velocity, pressure, and flow rate in a system. The continuity equation can be used to derive Bernoulli's equation for incompressible fluids.

The continuity of supply chain operations is crucial for business success.
Both are same..just the names are different.
Change means things are no longer as they once where. Continuity implies things staying on as they were.
The foramen magnum is the section that demonstrates the continuity between the spinal and cranial cavities. It is the large opening at the base of the skull through which the spinal cord passes.
The four statues of identity are uniqueness, continuity, category membership, and correlation. Uniqueness refers to what makes an individual different from others, continuity involves the consistency of characteristics over time, category membership relates to the groups an individual belongs to, and correlation refers to the connections between different aspects of identity.
