• Calculation of the hydraulic radius for various channel cross section shapes is an important part of using the Manning equation for open channel flow calculations. Three common open channel cross sections, the rectangle, trapezoid, and triangle, are covered in this article. The hydraulic radius for open channel flow is defined as the cross sectional area of flow divided by the wetted perimeter ...

• The angles that have the base as a side are the base angles. Legs Vertex angle Base Base angles Exterior Angle Theorem The measure of an exterior angle of a triangle is equal to the sum of the measures of its remote interior angles. An exterior angle IS an angle formed by one side of a polygon and the extension of an adjacent side.
• Corresponding Angle Theorem (and converse) : Corresponding angles are congruent if and only if the transversal that passes through two lines that are parallel. Same-Side Interior Angles Theorem (and converse) : Same Side Interior Angles are supplementary if and only if the transversal that passes through two lines that are parallel.
• Alternate Exterior Angles Theorem The Alternate Exterior Angles Theorem states that, when two parallel lines are cut by a transversal , the resulting alternate exterior angles are congruent . So, in the figure below, if k ∥ l , then ∠ 1 ≅ ∠ 7 and ∠ 4 ≅ ∠ 6 .
• Positive Displacement Flow Meter, FMC Series FMC series PD rotary vane meters are single case, angle-type, rotary vane, positive displacement meters. The positive displacement flow meter offers superior accuracy and metering for a wide range of products, such as, gasoline, kerosene, fuel oils, etc.
• Corresponding angles are the four pairs of angles that: have distinct vertex points, lie on the same side of the transversal and; one angle is interior and the other is exterior. Two lines are parallel if and only if the two angles of any pair of corresponding angles of any transversal are congruent (equal in measure).

These angles are acute angles, which means they are less than a right angle (less than 90°). Think of acute angles as sharp angles. If someone stabbed you with the vertex of an acute angle, it would feel sharp. The angle is opened even more now. It is an obtuse angle: an angle that is more than a right angle, yet less than a straight angle.
