Technician A says that to program EUI fuel flow rates to an ECM, some engines require a new engine file to be downloaded from the OEM data hub. Technician B says that failure to reprogram the calibration code on injector change-out can result is unlikely to cause any harm providing the engine runs smooth at idle after start-up. Who is correct?
A. Technician A only B. Technician B only C. Both A and B D. Neither A nor B
Consider a person standing in a room at 23°C. Determine the total rate of heat transfer from this person if the exposed surface area and the skin temperature of the person are 1.7 m2 and 32°C, respectively, and the convection heat transfer coefficient is 5?W/m2•K. Take the emissivity of the skin and the clothes to be 0.9, and assume the temperature of the inner surfaces of the room to be the same as the air temperature.

The initial cost of a packed-bed degassing reactor for removing trihalomethanes from potable water is $84,000. The annual operating cost for power, site maintenance, etc. is $13,000. If the salvage value of the pumps, blowers, and control systems is expected to be $9000 at the end of 10 years, the AW of the packed-bed reactor, at an interest rate of 8% per year, is closest to:
(a) $?26,140 (b) $?25,518 (c) $?24,900 (d) $?13,140
A fuse protects an electrical circuit by:
A) Using a material that limits the amount of current that can pass through the fuse due to the increase in the material's resistance. B) Melting when excessive current flows through it, opening the circuit. C) Using a heat motor that operates an imbedded set of contacts to open the circuit. D) Limiting the voltage that can flow through the fuse.
