The lecture delves into the topic of shock waves and different types of shock waves, including vertical and oblique shock waves. Shock waves are sudden changes in fluid properties that occur under specific conditions, such as supersonic flow.

The lecture focuses on the topic of shockwaves, specifically discussing the different types such as vertical and oblique shockwaves. Shockwaves are sudden changes in fluid properties that occur under specific conditions, primarily related to supersonic flow, and are characterized by discontinuities in properties.

The chapter discusses the vertical line one and two, where if a vertical line intersects the x-axis at one, the x remains the same. The chapter delves into the concept of shock waves and entropy changes, highlighting the discontinuity in functions at shock waves.

This chapter delves into the derivation of shock wave equations by analyzing the properties between points one and two in a control volume, focusing on mass, momentum, and energy conservation. Key relationships such as the pressure ratio across the shock wave and the stagnation temperature ratio are explored.

The chapter discusses the concept of normal shockwaves in airflow, focusing on upstream Mach numbers, pressure, temperature, and air velocity before and after the shockwave. It explains the calculations involved in determining properties like pressure ratios and airspeed ratios across the shockwave.
