A piece of experimental apparatus, Fig. $\mathrm{P} 1.83,$ is located where $g=9.5 \mathrm{~m} / \mathrm{s}^{2}$ and the temperature is $5^{\circ} \mathrm{C}$. Air flow inside the apparatus is determined by measuring the pressure drop across an orifice with a mercury manometer (see Problem 1.91 for density) showing a height difference of $200 \mathrm{~mm}$. What is the pressure drop in $\mathrm{kPa} ?$

Key Concepts

Hydrostatic Pressure

Hydrostatic pressure is the pressure exerted by a fluid at equilibrium due to the force of gravity. It is calculated based on the density of the fluid, the gravitational acceleration, and the height of the fluid column, and is fundamental to understanding how pressure differences arise in static fluids.

Manometer Measurement

A manometer is an instrument used to measure pressure differences by observing the height difference in a column of liquid. This device leverages the principles of hydrostatic pressure, where a difference in liquid column heights corresponds directly to a difference in pressure between two points.

Acceleration due to Gravity

Acceleration due to gravity plays a crucial role in fluid statics by affecting the hydrostatic pressure of a fluid. In pressure calculations, it appears as a multiplying factor with the fluid’s density and the height of the column, illustrating how gravitational force influences the pressure exerted by a fluid.

Unit Conversion in Pressure Calculations

Accurate pressure calculations require proper conversion between measurement units. This concept involves converting physical quantities such as the height of a liquid column to pressure units like pascals or kilopascals, ensuring consistency and correctness in the analysis of experimental data.
