use dimensional analysis to check if the expression P=(yv^2)/2 + ygh is correct. Given that P is pressure in pascal, y is densit
y in kgm^-3 , v is velocity in m/s, g is acceleration due to gravity in m/s^2 and h is the height in m(metre).
1 answer:
Answer: The expression is correct
Explanation:
We have the following expression:
Where:
Pressure: in units of Pascal ()
Density: in units of
Velocity: in units of
Acceleration due to gravity: in units of
Height: in units of
Knowing this, let's begin with the dimensional analysis:
Remembering , we are able to know this expression is correct.
