Pressure Recovery in a Subsonic Intake

Given Information:
- Stagnation pressure at the inlet of the intake = 100 kPa
- Stagnation pressure at the exit of the intake = 98 kPa

Understanding Pressure Recovery:
Pressure recovery is a measure of how effectively an intake system converts dynamic pressure (velocity) into static pressure. It indicates the extent to which the intake recovers the pressure that was lost during the deceleration of the flow.

Calculating Pressure Recovery:
To calculate the pressure recovery, we need to find the ratio of the stagnation pressure at the exit to the stagnation pressure at the inlet.

Formula:
Pressure Recovery = Stagnation Pressure at the Exit / Stagnation Pressure at the Inlet

Solution:
Given,
Stagnation Pressure at the Inlet = 100 kPa
Stagnation Pressure at the Exit = 98 kPa

Using the formula, we can calculate the pressure recovery as follows:

Pressure Recovery = 98 kPa / 100 kPa

Simplifying the expression, we get:

Pressure Recovery = 0.98

Final Answer:
The pressure recovery of the subsonic intake is 0.98.
