Root Mean Square Pressure given Sound Intensity Solution

STEP 0: Pre-Calculation Summary

Formula Used

Pressure RMS = sqrt(Sound Intensity Level*Density of Air*Velocity of Sound Wave)
P_rms = sqrt(I*ρ*C)
This formula uses 1 Functions, 4 Variables

Functions Used

sqrt - A square root function is a function that takes a non-negative number as an input and returns the square root of the given input number., sqrt(Number)

Variables Used

Pressure RMS - (Measured in Pascal) - The Pressure RMS refers to the root mean square value is the local pressure deviation from the ambient atmospheric pressure, caused by a sound wave.
Sound Intensity Level - (Measured in Watt per Square Meter) - The Sound Intensity Level refers to the logarithmic measure of the sound power per unit area, expressed in decibels (dB).
Density of Air - (Measured in Kilogram per Cubic Meter) - The Density of Air refers to the mass per unit volume of Earth's atmosphere, typically around 1.225 kg/m³ at sea level and 15°C, affecting sound propagation and weather.
Velocity of Sound Wave - (Measured in Meter per Second) - The Velocity of Sound Wave refers to the speed of sound with the distance traveled per unit of time by a sound wave.

STEP 1: Convert Input(s) to Base Unit

Sound Intensity Level: 1E-10 Watt per Square Meter --> 1E-10 Watt per Square Meter No Conversion Required
Density of Air: 1.293 Kilogram per Cubic Meter --> 1.293 Kilogram per Cubic Meter No Conversion Required
Velocity of Sound Wave: 343 Meter per Second --> 343 Meter per Second No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

P_rms = sqrt(I*ρ*C) --> sqrt(1E-10*1.293*343)

Evaluating ... ...

P_rms = 0.000210594159463172

STEP 3: Convert Result to Output's Unit

0.000210594159463172 Pascal --> No Conversion Required

FINAL ANSWER

0.000210594159463172 ≈ 0.000211 Pascal <-- Pressure RMS
