    Default MDPE hoop size??

    HI Guys,

    right I need a advice on hoop size? im building a diy poly tunnel. I have a 10ft wide bed which the hoop needs to cross. I plan to have 3ft straight sides before the hoop goes over to the other side. soooooooo the big question is how long does the MDPE pipe need to be cut? I sure someone will just work it out quickly, but I cant get my head round it. don't want to waste it by cutting it to short. lol

    3ft+3ft for verticals =6ft

    Half circle is as follows

    22/7 x 10/2( pi x d/2)
    =220/14
    =15.71428571428571

    Add two together
    =6+15.71428571428571
    =21.7ft then convert decimal places to inches
    Near as beep 21ft 8,5inches

    I want to know how your going to get the pipe to go from the three foot sraight sides into a curve then back to a straight side again?
    I would expect it to form an eclipse.

    Be aware when using longer lengths that they can sort of bend in & out, I had a begger of a job when I made the walk in Brassica cage & my hoops were only 13 foot.

    I make the straight sides I have treated broom handles. These fit perfectly into the 32mm MDPE pipe. Then these fit straight into 7ft scaffold poles I have put 4ft into the ground already. Thanks you the input guys much appreciated. :-)
