How is an oil furnace heat exchanger shaped?
What will be an ideal response?
The oil furnace heat exchanger is built like a drum with a donut around it. Combustion takes place in the drum and combustion gasses go from the drum to the donut before going up the flue.

Answer the following statement(s) true (T) or false (F)
1. Nearly all commercial, industrial, and residential power circuits are connected in parallel. 2. The total (line) current for an ac parallel circuit may not be equal to the arithmetic sum of the current in each of the branch circuits. 3. The power factor of the circuit is found by the use of the expression: PF = P + VI. 4. The apparent power or volt-amperes of the circuit can be determined by multiplying the applied voltage by the total current. 5. The amount of reactive power or VARs (volt-amperes-reactive) can be determined using the formula: VARs = P/VA.
Perform a PW-based after-tax replacement study from the information shown below using an after-tax MARR of 12% per year, Te of 35%, and a study period of 4 years. All monetary values are in $1000 units. Assume the assets will be traded at their original salvage estimates. Since no revenues are estimated, all taxes are negative and considered savings to the alternative. Solve by hand and by spreadsheet.
