Answer: b
Which of the following statements is TRUE
The density ,ρ, of any substance is its weight per unit volume.
The density ,ρ, of any substance is its mass per unit volume.
The density ,ρ, of any substance is its pressure per unit volume.
Answer: b
Which of the following statements about standard reference atmospheric or barometric
pressure (Po) is TRUE
a. The standard reference atmospheric or barometric pressure (Po) is 760 mm Hg 1abs or
29.92 in. Hg 1abs at 32°F, or 14.7 psia, or 1 atm.
b. The standard reference atmospheric or barometric pressure (Po) is 7000 mm Hg 1abs or
29.92 in. Hg 1abs at 32°F, or 14.7 psia, or 100 atm.
c. The standard reference atmospheric or barometric pressure (Po) is 770 m Hg 1abs or 30.60
in. Hg 1abs at 32°F, or 14.7 psia, or 1 atm.
Answer: a
Which of the following statements is FALSE
The specific volume of a substance is the ratio of the substance’s volume to its mass.
The specific weight is to the local acceleration of gravity as the density is to the standard
acceleration
The specific weight ,γ, of any substance is the force of gravity on unit mass.
Answer: c
Density is calculated by
Multiplying Weight by Volume
Dividing Mass by Volume
Dividing Weight by Volume
Answer: b
Specific weight can be calculated using the formula γ = ρg, where g is
9.8066 m/s
9.8806 m/s²
9.8066 m/s²
Answer: c
