The surface tension of water in air is approximately 0.00518 lbf/ft. if the atmospheric pressure is 14.7psia, what is the pressu
strojnjashka [21]

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.

Keith_Richards [23]

For a monopolist, if price is above average total cost, the monopolist is:

  • Earning positive or economic profit

<h3>What is positive profit?</h3>

A positive profit is earned when the revenue being made surpasses what is normal on the competitive scale. The cost of production is covered and surpassed in this case.

So when the monopolist fixes his price above the total cost, he will earn a positive profit.
