Problem: An oil layer floats on 80 cm of water in a tank. The pressure at the bottom of the tank is 111.0 kPa.How thick is the oil? Suppose that the density of oil is 900 kg/m3.
FREE Expert Solution
Pressure in fluids:
1 Pa = 1 N/m2
- ho = ?
- hw = 80 cm(1m/100cm) = 0.8 m
- ρo = 900 kg/m3
- ρw = 1000 kg/m3
- g = 9.8 m/s2
- Ptank = 111.0 kPa(1000Pa/1kPa) = 111000 Pa
- Patmosphere = 101325 N/m2
Pw = hwρwg = 0.8 × 1000 × 9.8 = 7840 N/m2
