Equivalent Airspeed given Static Pressure Solution

STEP 0: Pre-Calculation Summary

Formula Used

Equivalent Airspeed = Sonic Speed at Sea Level*Mach Number*(Static Pressure*6894.7573/Static Sea Level Pressure)^(0.5)
EAS = a_o*M*(P_static*6894.7573/P_o)^(0.5)
This formula uses 5 Variables

Variables Used

Equivalent Airspeed - (Measured in Meter per Second) - Equivalent Airspeed is calibrated airspeed corrected for the compressibility of air at a non-trivial Mach number.
Sonic Speed at Sea Level - (Measured in Meter per Second) - Sonic Speed at Sea Level is the speed of sound at sea level.
Mach Number - Mach Number (Ma) is a dimensionless quantity that represents the ratio of the speed of an object (such as an aircraft or projectile) to the speed of sound in the surrounding medium.
Static Pressure - (Measured in Pascal) - Static Pressure is the pressure exerted by a fluid (such as air or a gas) that is not in motion.
Static Sea Level Pressure - (Measured in Pascal) - Static Sea Level Pressure is the atmospheric pressure at sea level.

STEP 1: Convert Input(s) to Base Unit

Sonic Speed at Sea Level: 340 Meter per Second --> 340 Meter per Second No Conversion Required
Mach Number: 0.23 --> No Conversion Required
Static Pressure: 270 Pascal --> 270 Pascal No Conversion Required
Static Sea Level Pressure: 101325 Pascal --> 101325 Pascal No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

EAS = a_o*M*(P_static*6894.7573/P_o)^(0.5) --> 340*0.23*(270*6894.7573/101325)^(0.5)

Evaluating ... ...

EAS = 335.189048453538

STEP 3: Convert Result to Output's Unit

335.189048453538 Meter per Second --> No Conversion Required

FINAL ANSWER

335.189048453538 ≈ 335.189 Meter per Second <-- Equivalent Airspeed
