Question

A 70-cm-thick layer of oil floats on a 190-cm-thick layer of water. What is the pressure at the bottom of the water layer? ??????: 1.26?5 ?a

Answer 1

Answer #1

t_o =thickness of oil = 70 cm = 0.70 m

t_w = thickness of water = 190 cm = 1.90 m

P_o = atmospheric pressure = 101325 Pa

P_b = pressure at the bottom

pressure at the bottom is given as

P_b = P_o + g t_o + g t_w

P_b = 101325 + (1000) (9.8) (0.70) + (1000) (9.8) (1.90)

P_b = 126805 Pa = 1.26 x 10⁵ Pa
