6][ FLUIDA STATIS

ρb = 750 jg/m³
ρa = 1000 kg/m³... ANGGAP
Vm = __?

Vm = V - Vt
Vm = V - (ρb / ρa) V
Vm = V - (750/1000) V
Vm = V - ¾ V
Vm = ¼ V
Vm / V = ¼ = 25% ← jwb



7][ FLUIDA DINAMIS
b = besar, k = kecil
Ab = 400 mm², vb = 2 m/s
Ak = 100 mm². vk = __?

persamaan kontinuitas
Ak vk = Ab vb
vk = (Ab / Ak) • vb
vk = (400 / 100) • (2 m/s)
vk = 8 m/s ← jwb



8][ FLUIDA STATIS
k = kecil, b = besar
Ab = 10 m². mb = 2000 kg
Ak = 0,01 m². mk = __?

Fk / Ak = Fb / Ab
mk g / Ak = mb g / Ab
mk / Ak = mb / Ab
mk = (Ak / Ab) • mb
mk = (0,01 / 10) • (2000 kg)
mk = 2 kg ← jwb
