Tekanan Hidrostatis

Diketahui :

• ρ = massa jenis zat = 0.9 g/cm^3 = 900 kg/m^3
• g = gravitasi = 10 m/s
• Ph(A) = tekanan hidrostatis A = 3.600 N/m^2
• Ph(B) = tekanan hidrostatis B = 5.400 N/m^2

Ditanya :

• Selisih kedalaman ?

Jawaban

Cari kedalaman benda A

Ph = ρ × g × h

3.600 = 900 × 10 × h

3.600 = 9.000 × h

h = 3.600/9.000

h = 0.4 m

h = 40 cm

Cari kedalaman benda B

Ph = ρ × g × h

5.400 = 900 × 10 × h

5.400 = 9.000 × h

h = 5.400/9.000

h = 0.6 m

h = 60 cm

Selisih kedalaman A dan B:

Selisih = h(B) - h(A)

Selisih = 60 - 40

Selisih = 20 cm ✔
