The center-to-center dimension for a 45-degree bend is equal to the desired size of the offset times the cosecant 1.414. A cosecant is used to determine the distance between the centers of the two bends used to make an offset. A 45-degree angle has a cosecant of 1.414.
Know MoreAn angle's cosecant is defined as the length of the hypotenuse of a 90-degree triangle divided by the length of the opposite side of the triangle. According to the Porcupine Labor Press, other popular offset angles and their cosecants include 10 degrees with a cosecant of 5.76, 22.5 degrees with a cosecant of 2.6, 30 degrees with a cosecant of 2.0 and 60 degrees with a cosecant of 1.15.
Learn more about PlumbingWatts are equal to energy change in joules divided by time in seconds. Watts are a unit of power, which is the rate of energy change in a system, or the rate at which work is done. One watt equals an energy change rate of one joule per second.
Full Answer >The standard shower stall size is 3 feet by 3 feet. Most showers are larger than this to make them more appealing to home buyers, but regulations require the minimum be the 3 feet by 3 feet size so that people in wheelchairs can access them.
Full Answer >The pipe-fitting formula for a 45-degree offset in plumbing is the length of a diagonal connector, known as the travel, times 0.707. To calculate rolling offset, when a pipe changes direction both vertically and horizontally, it is necessary to find the values for true offset, the setback and the diagonal.
Full Answer >To calculate the water flow rate through a given pipe size, multiply the area of the inner cross-section of the pipe by the velocity of the water. The velocity of the water is required for this calculation.
