Description : A vacuum is connected to a tank reads 3kpa at a location w/ the barametric pressure reading is 75mmhg. Determined the P absolute in the tank  a. 70.658 kpa  b. 68 kpa  c. 58.78 kap  d. None of the above Pabs = Patm – Pvacuum

Last Answer : 70.658 kpa

According to Rankine's formula, the minimum depth of foundation (A) h = (P/W) [(1 - sin )/(1 + sin )]² (B) h = (w/P) [(1 - sin )/(1 + sin )]² (C) h = (P/w) [(1 - sin )/(1 + tan )]² (D) h = (P/w) [(1 - tan )/(1 + tan )]²
