1A correct fuel quotient becomes a performance guarantee
A fictional engine delivers 12000 kW continuously and consumes 2160 kg of fuel in one hour. The analyst calculates 180 g/kWh and compares it with a figure measured on another engine at a different load and with a different fuel heating value.
180 words, under 1 min2A pump-law estimate is mistaken for cooling approval
A fictional centrifugal pump operates at a reference speed and supplies a stated cooling duty. A classroom model assumes similar conditions and constant efficiency, then reduces speed to 80 percent and predicts power at 51.2 percent of the original.
173 words, under 1 min3A positive number is called a complete stability certificate
A supplied small-angle classroom model gives KM and KG, vessel displacement and a slack rectangular tank with an unrestricted free surface. A learner subtracts the corresponding correction and obtains a positive effective GM, then claims the vessel meets every intact and damaged stability requirement in every sea state.

At watch handover, a defect report records an unresolved fault in a standby system identified as critical by the vessel’s actual safety arrangements. An incoming engineer sees a log entry saying all systems normal, but no evidence shows that the defect was corrected or the standby function tested.

A fictional pressure transmitter is specified to produce four to twenty milliamperes over a zero-to-ten-bar measurement range. A displayed signal is twelve milliamperes.
157 words, under 1 min6The first-law sign convention is stated
A fictional closed gas system receives 500 joules of heat during a classroom process and does 180 joules of work on its surroundings. The supplied convention is change in internal energy equals heat added minus work done by the system.
