- Homework Statement
- I have a fluid mechanics textbook by Frank White which includes an example problem about a steady flow machine with one inlet and two outlets. The details of the actual problem are actually not so important as the follow: given information includes the areas of the inlets, the heat, the temperature, the pressure, and a height z. Included next to each given quantity is the unit in which its given. Next to heat, the unit is shown as (ft^3/s) where ft is feet and s is seconds. This is confusing me a bit. How can energy have those units? He subsequently even finds the fluid velocity at the inlets by dividing the heat by the inlet area, showing the units were not mistakenly typed. I am rather frustrated. Would anybody be able to explain how energy units would be length cubed over time?
- Relevant Equations
- Q (ft^3/s), A (ft^2), V (ft/s) => V = Q/A??? Where do the heat units come from??
Please and thank you!
