Question 1 (Compulsory): Steam nozzle efficiency calculations. Students are given initial pressure and temperature and must compute exit velocity using steam tables exclusively.
Question 2: IC Engine cycles (Otto and Diesel). A classic problem asks you to draw the P-V diagram and calculate air standard efficiency given compression ratios common in 1991 engines (e.g., 8:1).

Mechanical Technology is critical for addressing global skill shortages. By exposing students to technological processes from conceptual design to practical problem-solving, the curriculum prepares a new generation of technicians and engineers to maintain the infrastructure of the modern world. mechanical technology 91 question paper exclusive
