Q1:

The hydrostatic force acts through

A centre of pressure

B centre of top edge

C centre of bottom edge

D metacentre.

ANS:C - centre of bottom edge

In an inclined position, a venturimeter is likely to record a different reading compared to its reading in a vertical position. The exact change in reading depends on the angle of inclination and the direction of flow. Here's why:

  1. Effect of Gravity: When the venturimeter is inclined, gravity acts on the fluid differently compared to when it is in a vertical position. This can affect the pressure distribution within the venturimeter.
  2. Hydrostatic Pressure: In a vertical position, the hydrostatic pressure due to the height of fluid columns is balanced. However, in an inclined position, the pressure distribution along the inclined path may not be the same, leading to variations in the pressure readings.
  3. Flow Characteristics: The inclined position can affect the flow pattern and velocity distribution within the venturimeter, which in turn can influence the pressure readings.
Without knowing the specifics of the inclination angle and the flow conditions, it's difficult to determine whether the venturimeter will record more, less, or the same reading in an inclined position. The change in reading would need to be assessed experimentally or through detailed analysis considering the specific conditions. Therefore, the answer would be: None of these.
