The density of a fluid is given by the empirical equation 70 5 exp(8 27 10 )

where is density (lb /ft ) and is pressure (lb /in. ).

What are the units of 70.5 and 8 27 10 ?

Calculate the density in g/cm for a pressure of 9.00 10 N/m .

Derive a formula for (g/cm ) as a function of (N/m ). (See Example 2.6-1.) Check your resul
