Textbook Question
Chapter 1, Problem 25P
The kilogram force is commonly used in Europe as a unit of force. (As in the U.S. customary system, where 1 lbf is the force exerted by a mass of 1 lbm in standard gravity, 1 kgf is the force exerted by a mass of 1 kg in standard gravity.) Moderate pressures, such as those for auto or truck tires, are conveniently expressed in units of kgf/cm2. Convert 32 psig to these units.

The specific weight of a fluid is the product of the fluid's density and the acceleration
due to gravity.
Stronger surface tension leads to higher capillary rise.
Absolute pressures are frequently negative.
If the pressure of fluid drops below the vapor pressure of that fluid at that
temperature, the fluid will cavitate.

Density can be measured in lb;/ft° in the English system of units.
For a hydrostatic incompressible fluid, pressure is independent of depth.
A fluid with a high bulk modulus of elasticity is more difficult to compress than one
with a low bulk modulus of elasticity.
Viscosity is caused, in part, by the surface tension within a fluid.
A fluid can resist an applied shear stress by deforming.
Pressure increases faster with depth in less dense fluids than in more dense fluids.

A commonly used unit in everyday language to state weight is the pound (lb). There are actually several formal definitions of pound. One classification system defines a pound-mass (analogous to kg in SI units) and a pound-force (lbf) (analogous to a Newton); this is formally called English Engineering units but also commonly used in US Customary System units. The “pound” in the “pounds per square inch” of psi refers to pound-force. Hence, psi has units of force per area. Note that 1 lbf is defined as the gravitational force generated by 1 lb (mass) by multiplying it by the standard gravitational acceleration at the earth’s surface.
Starting with just the two everyday conversion approximations every Canadian should know (1.00 kg ≈ 2.20 lb (mass) and 1.00 inch ≈ 2.54 cm), derive an approximation of 1.00 psi in Pa through unit conversions only (show each step).
If the specific volume of a certain gas is 0.7848 m^3/kg, what is its specific gravity?
