What is a elbow of a pipe?
Generally it is a 90 degree fitting Some non knowing also call a 45 deg an ell as a 11 1/4 221/2 60 deg etc
What is principle sine function?
It is sine defined between -pi/2 and + pi/2 radians (-90 deg and +90 deg) and its inverse is defined over this range.
What kind of conduit does a 880 greenlee pipe bender bend emt or rigid?
A 770 Greenlee hydraulic pipe bender bend is used for rigid steel conduit from 2" to 4".
What is an equivalent of 90 degrees F in Celsius degrees?
Conversion: 90°F → (90 - 32) × 5/9 °C = 32 2/9 °C ≈ 32.22°C
Right angle is how many deg?
90 degrees. 1/2 pi radians.
What are the angles of rotation of a 20 gon?
Some 20-gons will have only one: 360 degrees. Some 20-gons will have 2 (180 deg), some will have 90 deg, 72 deg, 36 deg of 18 deg. It depends on the extent of irregularity of the polygon.
What is the firing order of a 4 rotor rotary engine?
1-3-2-4 Rotors 1&2(which are 180deg apart) are phased 90 deg from rotors 3&4 (which are 180 deg apart). Imagine a pair of 2 rotor eccentric shafts front to back, but the rear shaft is 90 deg offset to the front shaft.
What are the ratios of the length of the longer leg of a 30-60-90 triangle to the length of its hypotenuse?
The longer leg is opposite the 60 deg angle. Suppose A = 60 deg, C = 90 deg and a and c are the corresponding sides. Then, by the sine rule a/c = sin(A)/sin(C) a/c = sin(60)/sin(90) = sqrt(3)/2
What is the formula for computing the surface area of a pipe elbow?
Calculate as you would the surface of a cylinder who's height is the length of the central line of the pipe bend.(2*π*r*h)where:r is the (external) radius of the pipeπ is the constant 3.14159... andh is the length of the cylinder or the center-line of the pipe bend
What is take off measurement for 90 degree 8 inch pipe?
The take-off for a standard radius 90 is one and one half the diameter of the pipe. Example: 6 inch 90 has a take- off of 9 inches. The take-off for short radius 90 would be the dia. of the pipe. Long radius 90 is 2 times the pipe diameter.
What is relation between tangent and secant?
tan^2(x) + 1 = sec^2(x) for x not equal to odd multiples of pi/2 radians (90 deg).
What is the Take off measurements for 90 degree pipe fittings?
If it is 3 in. Then take off 3 in. and so on for what ever size you are use if it is 2 in. then 2 in.
