🔍 Key Concepts

• Engine power–speed curves and how they appear on an MCR (Maximum Continuous Rating) diagram • Difference between a propeller law curve and lines showing constant power or constant efficiency • How brake mean effective pressure (bmep) relates to horsepower and engine speed

💭 Think About

• Look at how line "P" is oriented: does it run along constant engine speed, constant power, or follow a curved relationship between speed and load? • Ask yourself which of the options would logically be drawn as a straight line versus a curved line on a power‑speed diagram. • Consider what happens to required power when propeller speed increases in still water—how would that relationship be sketched on a graph of % engine speed vs. % brake mean effective pressure?

✅ Before You Answer

• Verify what quantity is on the horizontal axis and what is on the vertical axis in this MO‑0126 diagram. • Check whether line "P" passes through the MCR point and how its shape compares to the shaded operating area and other slanted lines. • Confirm from basic propulsion theory whether a propeller curve is typically straight or curved when plotted against speed and load.
