Q6: For the manometer set up shown in the figure, the pressure difference P_A - P_B is given by

A (ρH - ρ_air)gH

B (ρH - ρL) gH + (ρL - ρ_air) . g(L - H)

C (ρH - ρL)gH

D (ρH - ρL) gL + (ρL - ρ_air)gH

ANS:A - (ρH - ρ_air)gH

It seems like you intended to describe a figure or diagram related to a manometer setup, but unfortunately, I cannot view or interpret images. However, I can help explain how to determine the pressure difference PA−PBP_A - P_BPA−PB in a typical manometer setup based on common configurations.

Manometer Basics:

A manometer is a device used to measure pressure differences between two points in a fluid by balancing the weight of the fluid between the two points. Here’s how you can determine PA−PBP_A - P_BPA−PB based on the setup:

Types of Manometers:
- Open-end Manometer: One end is open to the atmosphere.
- Closed-end (Differential) Manometer: Both ends are connected to different points in a system.
Calculation Method:
- For an open-end manometer, the pressure difference PA−PBP_A - P_BPA−PB is determined by the difference in the heights of the fluid columns in the two arms of the manometer. The pressure difference is given by: PA−PB=ρ⋅g⋅(hB−hA)P_A - P_B = \rho \cdot g \cdot (h_B - h_A)PA−PB=ρ⋅g⋅(hB−hA) where:
  - ρ\rhoρ is the density of the manometric fluid (typically mercury or water),
  - ggg is the acceleration due to gravity,
  - hAh_AhA and hBh_BhB are the heights of the fluid columns on the respective sides of the manometer.
- For a closed-end (differential) manometer, the pressure difference PA−PBP_A - P_BPA−PB is given by: PA−PB=ρ⋅g⋅(hA−hB)P_A - P_B = \rho \cdot g \cdot (h_A - h_B)PA−PB=ρ⋅g⋅(hA−hB) Here, hAh_AhA and hBh_BhB represent the heights of the fluid columns on the two sides of the manometer, typically relative to the same reference level.
Determining Pressure Difference:
- Identify which side (A or B) is connected to the higher pressure source.
- Measure the difference in height between the two fluid columns hAh_AhA and hBh_BhB.
- Use the formula appropriate for your manometer setup (open-end or closed-end) to calculate PA−PBP_A - P_BPA−PB.

Conclusion:

To provide a precise calculation for PA−PBP_A - P_BPA−PB, the specific details of the manometer setup, such as whether it's open-end or closed-end and the fluid used, are crucial. If you can describe the setup or provide additional details, I can help further with the calculation.
