SQ 1.1     The airflow required to heat a room is 2,500 cfm. If the heating coil temperature difference is 50°F, what is the required heating coil capacity in kilowatts?
SQ 1.2     Equivalent Uniform Annual Cost: EUAC = (Initial Cost x __________) + Annual Fixed Costs
SQ 1.3     Using Equivalent Uniform Annual Cost (EUAC), which of the following pieces of equipment is the best choice is the annual interest rate is 3.5%? (I) System 1: cost of equipment = $8750, useful life = 10 years, annual maintenance costs =$1000, (II) System 2: cost of equipment = $10,000, useful life = 11 years, annual maintenance costs =$750, (III) System 3: cost of equipment = $14,500, useful life = 14 years, annual maintenance costs =$250, (IV) System 4: cost of equipment = $9,250, useful life = 10 years, annual maintenance costs =$475
SQ 1.4     Calculate the Apparent Power (S) for a 120-volt inductive motor with a resistance of 35.9 ohms and an inductive reactance of 26.7 ohms. Power Factor Correction: Apparent power is measured in Volt-Amps, True power is measured in Watts, and Reactive power is measured in Volt-Amps-Reactive (VAR’s)
SQ 1.5     Calculate the True Power (P) for the 120-volt inductive motor in question SQ 1.4.
