Chapter 10, Problem 10.38SP

Interpretation Introduction

Interpretation:

Convert pounds per square inch into 1.00 atm and 1.00 mm Hg.

Concept introduction:

Pressure is force per unit area.

  $\begin{array}{c}P=\frac{F}{A}=\frac{N}{m^2}\\ =\frac{m\cdot a}{m^2}=\frac{kg\cdot \frac{m}{s^2}}{m^2}=\frac{kg}{m\cdot s^2}\end{array}$

Its unit is Newton per meter square or we can say kilogram per meter per second square. These two are not the only unit of pressure. The International system of unit (S.I unit) of pressure is Pascal, but these are not the only units of pressure there are more units of pressure like pounds per square inch, atmospheric (atm), mm Hg, torr etc.

To determine:

1.00 atm and 1.00 mm Hg is equal to Psi.
