Black Nipples

A nipple is a short piece of pipe with male pipe threads at both ends. It is used to join two threaded steel pipes. The length of the nipple is specified by the overall length including the threads. A close nipple has no unthreaded area and is virtually unexposed when connected to two fittings. Black nipples are manufactured of Get price

Fresnell's Equations: Reflection and Transmission

Reflection and Transmission Typical reflection and transmission curves for external reflection.These curves are the graphical representation of the Fresnel equations.Note that the reflected amplitude for the light polarized parallel to the incident plane is zero for a specific angle called the Brewster angle.

Mach Angle

Apr 06, 2018The sound waves strike the edge of the cone at a right angle and the speed of the sound wave is denoted by the letter a. The flow is moving at velocity v which is greater than a. From trigonometry, the sine of the cone angle mu is equal to the ratio of a and v: sin(mu) = a / v But the ratio of v to a is the Mach number of the flow. M = v / a Get price

THE MECHANICS OF TENSION CONTROL

Remember the equation of torque = tension x radius is linear, so torque must be decreased (for unwinds) and increased (for rewinds) at a linear rate relative to roll radius. For example, if you start with a 17.5 inch roll radius (35 inch diameter) and unwind down to a 1.75 inch core radius (3.5 inch diameter); 17.5 divided by 1.75 is 10:1 ratio. Get price

Pipe Pressure Drop Calculations Formula, Theory and Equations

Pipe Pressure Drop Calculations When fluid flows through a pipe there will be a pressure drop that occurs as a result of resistance to flow. There may also be a pressure gain/loss due a change in elevation between the start and end of the pipe. Get price

Tube and pipe basics: How to achieve the perfect bend

Other bending variables include the inside bend radius (sometimes called the intrados); the outside bend radius (or extrados); and the centerline radius or the neutral line, where neither compression nor stretching occurs.The bend angle refers to the complementary angle of bend. So if a tube is bent to "45 degrees," that's 45 degrees complementary, or a 135-degree included bend angle Get price

Flow in pipe

This formula has a wide application in the field of fluid mechanics and is used extensively throughout on this web site.

How to Work Out the Angles in a Triangle When the Angles

May 24, 2018Turn the expression from step 1 into an equation by making it equal to 180⁰ (since the angles in a triangle add up to 180⁰. Once this is done, you can solve the equation to find the value of x. 12x = 180. x = 180 12. x = 15⁰. Step 3. Once x is found, the size of each angle can be calculated by substituting x back into each angle. Get price

Arc Measure Formula

Arc Measure Definition. An arc is a segment of a circle around the circumference. An arc measure is an angle the arc makes at the center of a circle, whereas the arc length is the span along the arc. This angle measure can be in radians or degrees, and we can easily convert between each with the formula π r a d i a n s = 180 .. You can also measure the circumference, or distance around, a Get price

Difference Between Angle of Friction and Angle of Repose

Oct 07, 2015Angle of Friction is the angle made between the normal reaction force and the resultant force between friction and normal reaction force, when an object just begins to move along the surface. Angle of Repose is the shallowest angle of an incline where an object on it will begin to slide down. Get price

How to Calculate Taper Angle?

Step 2: To find the taper angle, its important to know taper value. To find taper substitute the values in formula. Taper = (dl - ds) / Length = (12 - 6) / 0.50 = 6 / 0.50 = 12 Step 3: We have taper value here. So we can find the Taper angle. Taper Angle = atan(0.5 x Taper) = atan (0.5 x 12) = atan(6) Taper angle = 1.4056 radians or 80.5377 Get price

The bank angle itself is directly related to the load factor. For any given load factor, there exists one specific bank angle. We can solve for that angle by rearranging one of our earlier equations to the form: The resulting bank angles required to maintain a level turn at a given load factor are illustrated below.
