Multiple Choice

FIGURE 13-1
-A reservoir manometer consists of a U-tube in which the two arms have different diameters, as shown in Fig. 13-1. The diameter on the narrow side is 10.0 mm and the diameter on the reservoir side is 25.0 mm. The liquid in the manometer is oil with a density of 830 kg/m³ and the fluids in contact with the oil are gases of negligible density. The dotted line indicates the level of the oil when the pressures p₁ and p₂ are equal. What is the value of h when P₁ - P₂ = 1000 Pa?

• A)10.6 cm
• B)12.3 cm
• C)8.40 cm
• D)9.81 cm
• E)13.2 cm
