Multiple Choice

FIGURE 15-4 FIGURE 15-4 -The circular pipes shown in Figure 15-4 both contain water, but at different pressures. They are connected by means of an inverted U-tube, which contains oil with a density of 800 kg/m<sup>3</sup>. The heights are: h<sub>A</sub> = 7.0 cm, h<sub>B</sub> = 20.0 cm, and h<sub>C</sub> = 13.0 cm. What is the pressure difference (P<sub>B</sub> - P<sub>A</sub>) ? A) 235 Pa B) 240 Pa C) 255 Pa D) 270 Pa E) 285 Pa
