4. Calculate the pressure difference between the inside and outside of a water droplet with a diameter of 1/16 in at 70 °F. Hint: use the surface tension value in Appendix B of the book.

A tiny steel cube is suspended in water by a string .if the lengths of the sides of the cube are very small ,how would you compare the magnitude of the pressure on the top ,bottom and sides surfaces of the cube .

What is the absolute pressure inside a water drop having radius 1mm and surface tension as 0.1 N/m? Assume atmospheric pressure as 1 bar.

A soap bubble 50 mm in diameter contains a pressure (in excess of atmospheric) of 2 bar. Find the surface tension in the soap film.

The absolute pressure in a gas tank is 300 kPa.   Determine the gage pressure. Calculate the pressure head in meters of mercury.

A tiny steel cube is suspended in water by a string. If the lengths of the sides of the cube are very small, how would you compare the magnitudes of the pressures on the top, bottom, and side surfaces of the cube?

pressurea are sometimes determined by measuring the height of a column of liquid in a vertical tube, what diameter clean glass tubing is required so that the rise of the water at 20°C in a tube due to capillary action (as opposed to pressure in tube) is less than h=1.0mm

Assuming specific weight of air to be constant, what is the approximate height of Mount Banahaw in m if a mercury barometer at the base of the mountain reads 654 mm and at the same instant, another barometer at the top of the mountain reads 480 mm?

If the PO2 is 100 mm Hg at one barometric pressure (760 mm Hg), what is the approximate PO2 if the pressure is increased to 1,520 mm Hg in a hyperbaric chamber?
