Pipe Drawing Arithmetic: Offset Projections and Supplied Takeouts

Pipe Drawing Arithmetic: Offset Projections and Supplied Takeouts

Original quantitative learning practice in English. All 24 questions are included. Four supplied cases exercise six related calculation targets; they form one topic, not four separate tests. Every question includes the complete initial data. Use the stated model and retain intermediate precision. Choose one answer. Learning target: 20/24, not an official pass mark. This bank covers the calculation topic in its title; it is not a complete professional examination, design approval or operating instruction.

A model offset has perpendicular projections 300 and 400 mm in a 3:4 ratio. The diagonal centre-to-centre length is therefore 5/3 times x. Each of its two fittings occupies a supplied 40 mm along that diagonal. A horizontal straight extension of 600 mm follows. Ignore joints beyond these stated takeouts; no fitting standard is assumed. Calculate the combined straight cut lengths in mm. Keep intermediate values unrounded; round the final result to four decimal places if necessary.
