Air at 800 kPa and 1200 K enters a converging nozzle with negligible velocity (i.e., these are stagnation or total values). The throat area of the nozzle is 10 cm?. Calculate and plot the exit pressure, exit velocity, and mass flow rate versus back pressure (exit pressures) from 100 kPa to 800 kPa by 100 kPa.

Engineering Drawing

Technical drawing has been around since ancient times. As in the ancient Renaissance, complicated drawings were created, including Leonardo da Vinci's drawing. Modern engineering drawing, including its specific orthographic projection with scale conventions, began in Europe (France) during the early stages of Industrialization. L.T. C. Rolt also made some of Marc's drawings for its block-making machinery (in 1799) that also may have contributed significantly to British engineering technology. Since he learned the art of presenting three-dimensional(3D) items in a two-dimensional(2D) plane, as we now term mechanical drawing.
