+33661 We divide by 1000 to turn that term into kilo pascals (kPa). Without that the first term would be in pascals. I could, of course, have simply multiplied the second term by 1000 to get it into pascals before adding the rho*g*h term, but would then have had to divide the result of the summation to get it back to kPa, as the possible answers are given in kPa.
+33661 If we take the density of blood as 1060 kg/m^3 (just a little thicker than water!) and g = 9.8m/s^2 then:
PF = 1060*9.8*1.7/1000 + 13.3 kPa or PF ≈ 30.96 kPa
