MKC SWE FINAL EXAM SCRIPT 2026
COMPLETE QUESTIONS AND ANSWERS
GRADED A+
◉hydraulic aeration if there is no leak. Answer: Low Fluid
◉Air leaks in the hydraulic pump. Answer: Sharp Cracking,
Fluttering of PSI Gauge needle
◉Most common type of hydraulic fluid. Answer: Petroleum based
◉Viscosity Index VI. Answer: Fluid resistance to viscosity changes
with temperature changes
Higher the number more stable the fluid
◉Smallest particle visible to naked eye. Answer: 40 micron
◉Heat flow. Answer: From Warm to Cool
, ◉HVAC Pre-Heaters. Answer: Removes condensation from air
supply
◉AC compression. Answer: takes place in the compressor vapor
temp is raised above the cooling medium
◉AC condensation. Answer: Takes place in the condenser. Superheat
is removed from vapor, refregerant condenses giving latent heat to
cooling medium. Liquid is subcooled
◉AC expansion. Answer: Takes place at the metering device high
temp refrigerant passes thru orfice rapidly expanding in volume.
expansion lower pressure
◉AC evaporation. Answer: Takes place in evaporator. Refrigerant
will absorb latent heat and will flash off into vapor. Vaporized
refrigerant will become supeheated
◉Hydro test stainless air receiver. Answer: 15 years
◉Hydro test carbon steel air receiver. Answer: 10 years
◉Hydro test Aluminum and non ferrous metal. Answer: 6 years
