hm = 2 cm = 0,02 m
pc = 1000 kg/m^3
pm = 0,8 g/cm^3 = 800 Kg/m^3
g = 9,8 m/s^2
Dit Ph total ?
jawab
Ph c = pgh
= 1000. 9,8 . 0,08
= 784 kg/m^3
Ph m = pgh
= 800 . 9,8 .0,0 2
= 156,8 kg/m^3
P tot = Phc + Phm
= 784 + 156,8
= 940, 8 kg/m^3 / 941 Pa <--
Semoga membantu :) D jadikan jawaban terbaik ya ^^
Hminyak = 2 cm = 0,02 m
Pcair = 1000 kg/m^3
Pminyak = 0,8 g/cm^3 = 800 Kg/m^3
g = 9,8 m/s^2
Dit Ph keseluruhan ?
Ph cair = pgh
= 1000. 9,8 . 0,08
= 784 kg/m^3
Ph minyak = pgh
= 800 . 9,8 .0,0 2
= 156,8 kg/m^3
Pkes = PhCair + Phminyak
= 784 + 156,8
= 940, 8 kg/m^3 atau 941 Pa
jadi jawabannya D
