GATE ME case studies
GATE ME · Put your knowledge to work in context.
GATE Mechanical Engineering (GATE ME) is a national-level postgraduate engineering entrance and recruitment screening examination administered by the Indian Institutes of Technology on behalf of the National Coordination Board. A qualifying GATE ME score is used for admission to M.Tech, MS, and doctoral programmes at IITs, NITs, and IISc, and is also accepted by many public-sector undertakings for recruitment to engineer posts. The GATE ME case studies are 5 cases and about 3,439 words.
1Thermocouple Calibration: When an Exact Fit Is the Wrong Fit
A junior engineer is calibrating a type-K thermocouple against a certified bath. Six readings are recorded at 0, 20, 40, 60, 80 and 100 °C, with EMF values 0.000, 0.798, 1.611, 2.438, 3.280 and 4.138 mV.
