Haddii aad ku cusub tahay tubbada ama warshadaha tubada daawaha ama aad ganacsiga ku jirtay sanado, ereyga "Jadwalka 40" kuma cusba adiga.Kaliya maaha erey fudud, waa mitirka muhiimka ah, markaa aynu yara sii qoto dheereyno oo aan ogaano sababta Jadwalka 40 uu caan u yahay!
Waa maxay Jadwalka 40
Tuubbada Jadwalka 40 waa tuubo leh dhumuc gaar ah oo gidaar ah.Dhumucdiisuna waxay ku xidhan tahay dhexroorka dibadda ee tuubada.Tani waa sababta oo ah lambarka ka dambeeya Jadwalka si toos ah uma tixraacayo dhumucda gidaarka gaarka ah, laakiin waa kala soocid.
Habka xisaabinta nambarka Jadwalka waa hab la fududeeyay oo lagu qiyaaso xidhiidhka ka dhexeeya dhumucda gidaarka tuubada iyo cadaadiska la saarayo.
Habkani waa sida soo socota:
Tirada Jadwalka = 1000 (P/S)
Pwaxay ka dhigan tahay cadaadiska shaqada ee naqshadeynta tuubada, badiyaa psi (pounds per square)
Swaxay ka dhigan tahay culayska ugu yar ee la ogol yahay ee walxaha tuubada ee heerkulka shaqaynaysa, sidoo kale psi (pounds per square).
Habkani waxa uu bixiyaa qaab-dhismeedka aragti ee fahamka xidhiidhka ka dhexeeya dhumucda tuubooyinka leh qiyamka Jadwalka kala duwan iyo cadaadiska ugu badan ee ay si ammaan ah u adkeysan karaan.Ficil ahaan, Qiimaha Jadwalka ee tuubbada waxaa lagu sii qeexay heerka.
