The problems for the afternoon section in the NCEES "Sample Questions + Solutions" book are numbered 501 through 540. This post is about Problem 506 of the Thermal and Fluid Systems sample exam.
Description & Analysis of Problem 506: This is a relatively straightforward U-tube manometer problem. The configuration is very simple and is similar to what is found as a solved example in any Fluid Mechanics or Thermodynamics textbook. The following problem is inspired by a solved example in "Fundamentals of Fluid Mechanics" 6th edition, by Munson, et al. and is only slightly more complicated than Problem 506.
