Based on the calculations, the pressure inside this droplet is equal to 2,909.35 kPa.
<u>Given the following data:</u>
- Surface tension = 0.00518 lbf/ft to N/m = 0.00702 N/m.
- Atmospheric pressure = 14.7psia to kPa = 101.35 kPa.
- Diameter = 0.01 mm to m = 0.00001 m.
Radius, r =
= 0.000005 m.
<h3>How to determine the pressure inside a droplet.</h3>
For a droplet with only one surface, its pressure is given by this formula:

Substituting the given parameters into the formula, we have;

The Equation for parabola is y=-1/486 x² +6 and the height of the arc 5 feet is: 5 461/486 feet.
<h3>
Equation for parabola</h3>
Using this equation to find the equation for parabola
y=a(x-54) (x+54)
y(0)=a(-54) (54)=6
-2916a=6
Divide both side by y6a
a=-2916/6
a=-486
Equation for parabola
y=-1/486 x² +6
Height of the arc 5 feet
When x=5
y=-25/486+6
y=2891/486
=5 461/486 feet
Therefore the Equation for parabola is y=-1/486 x² +6 and the height of the arc 5 feet is: 5 461/486 feet.
