h1-2 =1,388+1,019 =2,4 m p1-2 = h1-2 g bar p1-2 =2,4*860*9,81 =20248 Pa =0,2 bar Vastus: Kui torustiku pikkus on 25 m, on rõhukadu meetrites 2,4 m ja baarides 0,2 bar. Ülesanne 8 Antud: Hüdrosilindri kaugus pumbast: h =10 m Minimaalselt nõutav töörõhk silindris: pt =63 bar =6300000 N/m2 =63*105 Pa Eelmises ülesandes leidsime, et rõhukadu 25 m pikas torustikus on baarides 0,2 bar. Et leida kui palju on rõhukadu 10 m pikas torus on vaja rõhukadu jagada 2,5-ga. p1-2 Rõhukadu baarides: 6 0,2 2,5 =0,08 bar
Step-down method (sequential allocation method) allocates support-dept costs to other support departments and to operating departments in a sequential manner that partially recognizes the mutual service provided among all support depts. This method requires support depts to be ranked. Reciprocal method allocates support-dept costs to operating depts by fully recognizing the mutual services provided among all support depts. 1) PM = 6300000+0.1IS; IS = 1452150+0.2PM; to get the number of complete reciprocated costs of PM and IS. 2) allocate the complete reciprocated cost of each support dept to all other depts (support and operating) on the basis of the usage %. Common cost is a cost of operating a facility, activity, or like cost object that is shared by two or more users. Stand-alone cost-allocation method determines the weights for cost allocation by considering each user of the cost as a separate entity
