5/7/2018 Fluids
« on: May 07, 2018, 07:42:48 AM »
Question:

Use the attached manometer diagram shown below for reference.  What is the pressure difference in KPa?

Assume the dark liquid is mercury with a density of 13.6 gm/cm^3 and the light liquid is water with a density of 1 gm/cm^3.   

No multiple choice!

I hate SI units !   Are both units on the real exam?

yes... so you better get used to solving both ways! I think SI is easy compared to English.

Why can't I find the manometer equation in the handbook?  WTF?

don't really need an equation, just set up the bernoulli equation across the device. I think I have it solved.  I'll post it when I double check my solution.

see page 110 of the FE Handbook for the equation.

= (20 cm)(980 cm/s^2)(12.6 g/cm^3)

= 247,000 g/cm-s^2
