Identification should include a measurement of a force divided by rate using units appropriate to the energy system.
Examples of appropriate units should include
- mechanical—lb/(ft/sec) or N/(m/sec)
- fluid—lb/in2 /(gal/min) or N/m2/(m3/sec)
- electrical—V/I or ohms
- thermal—F/(Btu/hr) or C/(Cal/hr).
Process/Skill Questions:
- What would happen if the wrong unit is used?
- What is the SI or English unit for mechanical resistance?
- What is the SI or English unit for fluid resistance?
- What is the SI or English unit for electrical resistance?
- What is the SI or English unit for thermal resistance?
