Is a radius a diameter?
Radius, Diameter and Circumference The Radius is the distance from the center outwards. The Diameter goes straight across the circle, through the center. The Circumference is the distance once around the circle.
What is the half of radius?
In either case, the radius may be more than half the diameter, which is usually defined as the maximum distance between any two points of the figure. The inradius of a geometric figure is usually the radius of the largest circle or sphere contained in it.
Is radius diameter divided by 2?
The diameter of a circle is the distance across a circle directly through its center. The radius is one half of the diameter in measurement. Use the diameter to find the radius by dividing the diameter by 2. For example, if the diameter is 4, the radius would be 2.
What is L D ratio of extruder?
The L/D ratio is the ratio of the flighted length of the screw to its outside diameter. The ratio calculation is calculated by dividing the flighted length of the screw by its nominal diameter.
What is L D ratio of reactor?
From a processing perspective the optimum height to diameter of a stirred vessel is almost always between L/D=1.0 and L/D=0.8, with a single impeller.
How do you determine the thickness of a reactor?
hoop-stress formula for wall thickness:
- t= vessel wall thickness, in.
- P= design pressure difference between inside and outside of vessel, psig.
- R= inside radius of steel vessel, in.
- S= maximum allowable stress for the steel.
- E= joint efficiency (≈0.9)
- tc=corrosion allowance = 0.125 in.
What is the diameter of a 24 foot circle?
Diameter of a Circle
How do you find the radius of a circle with coordinates?
The equation of a circle with center (h,k) and radius r units is (x−h)2+(y−k)2=r2 .
Is the radius of a circle a chord?
The radius of a circle is any line segment connecting the centre of the circle to any point on the circle. The chord of a circle is a line segment joining any two points on the circle. The chord of a circle which passes through the centre of the circle is called the diameter of the circle.
How do you find radius?
Divide the diameter by two. radius is always half the length of its diameter. For example, if the diameter is 4 cm, the radius equals 4 cm ÷ 2 = 2 cm.
