Math Problem Statement

I need to solve this

Calculate the height h given the hydrostatic pressure equation. Round the result to one decimal place.

Solution

To solve this problem, we need to find the height hh using the formula for hydrostatic pressure:

ph=ρghp_h = \rho \cdot g \cdot h

Where:

  • php_h is the hydrostatic pressure, given as 17773.517773.5 Pa.
  • ρ\rho is the density of the fluid, given as 867kg/m3867 \, \text{kg/m}^3.
  • gg is the acceleration due to gravity, given as 10N/kg10 \, \text{N/kg}.

We need to rearrange the equation to solve for hh:

h=phρgh = \frac{p_h}{\rho \cdot g}

Now plug in the given values:

h=17773.5867×10h = \frac{17773.5}{867 \times 10}

h=17773.58670h = \frac{17773.5}{8670}

h2.05mh \approx 2.05 \, \text{m}

Since the problem asks for the height in centimeters, convert meters to centimeters:

h205cmh \approx 205 \, \text{cm}

Thus, the height hh is approximately 205cm205 \, \text{cm}, rounded to one decimal place, it is 205.0cm205.0 \, \text{cm}.

Here are 5 related questions to consider:

  1. What is hydrostatic pressure and how is it derived?
  2. How does fluid density affect hydrostatic pressure?
  3. What units are commonly used for measuring pressure, density, and height?
  4. How does gravitational acceleration vary on different planets?
  5. Why is the unit conversion necessary in this type of calculation?

Tip: When solving for variables in physics, always ensure the units are consistent throughout the equation to avoid calculation errors.
