Question: The range of wavelengths for shortwave radiation is approximately: ((MCAER 2014))
Options:
Mechanical output to specific fuel consumed per hour
Brake horsepower to indicated horsepower
Thermal efficiency to mechanical efficiency
Mechanical output to specific fuel consumed per minute
✅Explanation: Mechanical efficiency is the ratio of the mechanical output power of an engine to the specific fuel consumed per hour. It measures how efficiently the engine converts fuel energy into mechanical work.
