Which of the following is dimensionally correct
Which of the following is dimensionally correct
Pressure = Energy per unit area
Pressure = Energy per unit volume
Pressure = Force per unit volume
Pressure = Momentum per unit volume per unit time
Which of the following is dimensionally correct
Pressure = $\frac{{{\rm{Force }}}}{{{\rm{Area}}}} = \frac{{{\rm{Energy}}}}{{{\rm{Volume}}}}$= $M{L^{ - 1}}{T^{ - 2}}$
