In this article (and video above), I solve a fluid dynamics question that would fall under the water resources and hydrology section of the FE exam, similar to what you may encounter during the exam.
A 500 mm circular pipe carries a flow of 0.28 m3/s of water under a pressure of 0.34 cm, mercury (Hg). If the pipe is laid at an elevation of 9.3 m above a reference datum, then the total head (m) with respect to the reference datum is most nearly:
- 9.45 m
- 9.37 m
- 9.66 m
- 9.71 m
