Mach number given Impact and Static pressure Solution

STEP 0: Pre-Calculation Summary
Formula Used
Mach number = (5*((((Impact Pressure/Static pressure)+1)^(2/7))-1))^(0.5)
M = (5*((((qc/p)+1)^(2/7))-1))^(0.5)
This formula uses 2 Variables
Variables Used
Impact Pressure - Impact Pressure is the difference between total pressure and static pressure. (Measured in Pascal)
Static pressure - Static pressure is defined as the actual pressure of the fluid, which is associated not with its motion but with its state. (Measured in Pascal)
STEP 1: Convert Input(s) to Base Unit
Impact Pressure: 10 Pascal --> 10 Pascal No Conversion Required
Static pressure: 100 Pascal --> 100 Pascal No Conversion Required
STEP 2: Evaluate Formula
Substituting Input Values in Formula
M = (5*((((qc/p)+1)^(2/7))-1))^(0.5) --> (5*((((10/100)+1)^(2/7))-1))^(0.5)
Evaluating ... ...
M = 0.37152150228396
STEP 3: Convert Result to Output's Unit
0.37152150228396 --> No Conversion Required
FINAL ANSWER
0.37152150228396 <-- Mach number

Mach Number behind the shock
Mach Number behind shock = ((2+(Specific Heat Ratio*(Mach Number ahead of shock^2))-(Mach Number ahead of shock^2))/((2*Specific Heat Ratio*(Mach Number ahead of shock^2))-Specific Heat Ratio+1))^(1/2) Go
Static Pressure behind of normal shock using normal shock momentum equation
Static pressure behind shock = Static pressure ahead of shock+(Density ahead of shock*(Velocity upstream of shock^2))-(Density behind shock*(Velocity downstream of shock^2)) Go
Static Pressure ahead of normal shock using normal shock momentum equation
Static pressure ahead of shock = Static pressure behind shock+(Density behind shock*(Velocity downstream of shock^2))-(Density ahead of shock*(Velocity upstream of shock^2)) Go
Velocity behind a normal shock
Velocity downstream of shock = Velocity upstream of shock/((Specific Heat Ratio+1)/((Specific Heat Ratio-1)+(2/(Mach Number ahead of shock^2)))) Go
Entropy change across normal shock
Change in Entropy = Specific gas constant*ln(Stagnation pressure ahead of shock/Stagnation pressure behind shock) Go
Relation between Characteristic Mach number and Mach number
Characteristic Mach number = ((Specific Heat Ratio+1)/((Specific Heat Ratio-1)+(2/(Mach Number^2))))^0.5 Go
Shock strength
Shock Strength = (2*Specific Heat Ratio/(1+Specific Heat Ratio))*((Mach Number ahead of shock^2)-1) Go
Prandtl Condition
Velocity downstream of shock = (Critical speed of sound^2)/Velocity upstream of shock Go
Characteristic Mach number
Characteristic Mach number = Fluid Velocity/Critical speed of sound Go
Characteristic Mach Number behind shock
Characteristic Mach number behind shock = 1/Characteristic Mach number ahead of shock Go
