Question
The pressure energy per unit when of a liquid is
- p/ρ
- P
- P.ρ
- ρ/p
Answer
p/ρ
Explanation
Pressure is defined as force per unit area, and its SI unit is the Pascal (Pa). Density is defined as mass per unit volume, and its SI unit is kg/m3. Therefore, the unit of pressure energy per unit volume is the Joule per cubic meter (J/m3).
