Fluid Mechanics

a) The hydrostatic equation is: (p/gamma)+z=C, where p is pressure, gamma is specific weight, and C is a constant. Show that this equation is dimensionally homogeneous.

b) Would a check for dimensionless homogenity have saved the Mars Climate Orbiter? Why or why not?

Step 1

The hydrostatic equation is given, and it is to be shown that it is dimensionally homogeneous. This can be done as,

Step 2

Substituting all the respective dimensions in the equation, we get,

Step 3

Now since on the LHS of the equation, we have a dimension of length for both and Z. Therefore, the c...
