Elemen Analisis

Solusi :

1.       350 psi = 6.895 x 350 kPa

= 2413.25 kPa                                           à = 2413.25/98.0665 Kgf/cm²

= 2413.25 x 10³  MPa                                      = 24.6 Kgf/cm²

2.       σ  = 15000 psi

       = 15000 x 6.895 kPa                                                     à = 10345/98.0665 Kgf/ cm²

       = 1.0345 x 10⁸ MPa                                                             = 1054.64 Kgf/100 mm²

                                                                                                     = 10.5464 Kgf/mm²

3.       St.37,S_u = 37 Kgf/mm²

= (3.7 x 10³  x 98.0665)/6.895 psi

= 52,62 x 10³ psi

4.       γ  = 7.8 Kgf/dm³

      = (7.8 /4.448) lbf/ (10^-3 / 6,1 x 10⁴) in³

5.       E = 200 GPa

   = 2 x 10⁸  kPa / 6,895

   = 2,9 x 10⁷ psi

6.       LNG 1 x 10⁴ kcal/m³ = 4.314 x 10⁸ kWh/m³

       = 4.314 x10⁶ / 0,293 x 35.313   MM Btu/ft³

       = 4.17 x 10⁵  MM Btu/ft³

1 US gallon = 0.134 ft³

                       = 231 in³

5 US gallon = 1155 in³

v_mouth = 0.9 in³

n_mouth = 1155/0.9

           = 1283,3

           = 1,29 x 10³ mouthful
