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 = \frac{diamter}{2} =\frac{0.0001}{2} = 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:

P_1-P_2=\frac{2 \tau}{r} \\\\P_1=\frac{2 \tau}{r}+P_2

Substituting the given parameters into the formula, we have;

P_1=\frac{2 \times 0.00702}{0.000005} + 101.35\\\\P_1=2808+ 101.35

Inside pressure = 2,909.35 kPa.

Monitors manufactured by TSI Electronics have life spans that have a normal distribution with a standard deviation of 1500 hours
FromTheMoon [43]

Answer:

0.2776

Explanation:

Mean = 15000, SD = 1500

We need to find Cumulative probability: P(X > 15884)

First we need to convert it into normal distribution.

From the attached file, we can see the shaded area we are looking for.

For conversion as follow; P (X>15884) =P ( X - mean > 15884-15000 ) =P (\frac{X- mean}{SD} > \frac{15884-15000}{1500} )

Next to find Z = \frac{X- mean}{SD} = 0.59

now we have converted to normal distribution and found the value of Z, we need to find the probability P(X > 15884).

P(X > 15884) = P(Z > 0.59).

From the normal distribution table at Z= 0.59, and greater than 0.59, Probability = 0.2776.
