The density of a fluid is given by the empirical equation p = 70.5 exp (8.27 x 10-7p) where p is density (lbm/ft3) and P is pressure (lbf/in.2).
(a) What are the units of 70.5 and 8.27 x 10-7?
(b) Calculate the density in g/cm3 for a pressure of 9.00 x 106 N/m2.
(c) Derive a formula for p(g/cm3) as a function of P(N/m2). (See Example 2.6-1) Check your result using the solution of part (b).
