## About Pressure Ratio Calculator (Formula)

The Pressure Ratio Calculator is a tool used to calculate the pressure ratio between the exhaust pressure and the inlet pressure. This calculator is particularly useful in various engineering applications, such as gas turbines, compressors, and combustion engines, where the pressure ratio plays a critical role in determining performance characteristics.

The pressure ratio represents the ratio of the exhaust pressure to the inlet pressure and is typically expressed as a percentage. It provides valuable information about the compression or expansion of a fluid within a system. The formula used to calculate the pressure ratio is as follows:

Pressure Ratio (%) = (Exhaust Pressure / Inlet Pressure) * 100

In this formula, the exhaust pressure is the pressure at the outlet or exhaust of the system, measured in pounds per square inch (psi), while the inlet pressure is the pressure at the inlet or intake of the system, also measured in psi. By dividing the exhaust pressure by the inlet pressure and multiplying the result by 100, we obtain the pressure ratio expressed as a percentage.

The Pressure Ratio Calculator simplifies this calculation by allowing users to input the exhaust pressure and the inlet pressure into the designated fields. Upon clicking the “Calculate” button, the calculator applies the formula and displays the pressure ratio in the corresponding output field.

This tool proves beneficial in engineering and design processes, enabling engineers and professionals to evaluate and optimize system performance based on the pressure ratio. It assists in determining the efficiency, power output, and overall effectiveness of various systems that involve fluid compression or expansion.

By using the Pressure Ratio Calculator, engineers can quickly assess the impact of pressure changes on system behaviour, make informed decisions regarding system design or modification, and ultimately achieve desired performance characteristics in their applications.
