Which three factors mainly determine the capital cost of a piece of equipment at a given time?

• A. Location, operator skill, and energy efficiency
• B. Age, maintenance history, and safety rating
• C. Size or capacity, material of construction, and operating pressure
• D. Color, supplier, and warranty period

Answer: (C)

Capital cost is driven by design characteristics that determine how much material, fabrication, and safety work the unit requires. The size or capacity sets the scale: a larger unit means more metal, bigger dimensions, more complex fabrication, and greater install load, all of which raise the purchase price and the upfront engineering effort. The material of construction matters because different materials have different base prices, fabrication challenges, and compatibility requirements; moving from carbon steel to stainless steel or a corrosion-resistant alloy can significantly change both raw material costs and the complexity of welding, inspection, and testing. The operating pressure is a design constraint that often dictates wall thickness, reinforcement, and adherence to strict codes and testing; higher pressure vessels need thicker walls, additional safety features, and more rigorous verification, all contributing to a higher capital cost. Other factors tend to influence operating costs or installation logistics rather than the inherent purchase price. Location, operator skill, and energy efficiency affect how much it costs to run or service the equipment or to install it in a given place, but not the baseline capital cost of the unit itself. Age, maintenance history, and safety rating can impact retrofit needs or resale value, not the initial price. Color, supplier choice, and warranty period are mostly cosmetic or after-sale considerations and generally have a minor or indirect effect on the upfront capital cost.
