Prandtl-Meyer Expansion Velocity Calculator:
Enter the values of Specific heat ratio y to determine the value of Prandtl-Meyer Expansion Velocity Vmax(m/s) .
Prandtl-Meyer Expansion Velocity Formula:
The Prandtl-Meyer Expansion Velocity Vmax(m/s) in meter per second is equal to the 3.141 and divided by the value of 2 into multiply the SQRT of Specific heat ratio (y) to addition of the value 1 and divided by the Specific heat ratio (y) to subtracted by the value of 1 into again subtracted by the value of 1.
The Formula of Prandtl-Meyer Expansion Velocity can be writtern as,
Vmax(m/s) = pi / 2 * ( SQRT ( y + 1 ) / ( y – 1 ) ) – 1 )
Here,
Vmax(m/s) = Prandtl-Meyer Expansion Velocity in meter per second
y = Specific heat ratio
Calculation for Prandtl-Meyer Expansion Velocity:
1)Determine the Prandtl-Meyer Expansion Velocity and given for y = 1.50.
Answer
Vmax = pi / 2 * ( SQRT ( y + 1 ) / ( y – 1 ) ) – 1 )
Vmax = 3.141 /2 * ( SQRT ( 1.50 + 1 ) / ( 1.50 – 1 ) ) – 1 )
Vmax = 2.51m/s.
2)Determine the Specific heat ratio and given for Prandtl-Meyer Expansion Velocity = 2.51m/s.
Answer
Vmax = pi / 2 * ( SQRT ( y + 1 ) / ( y – 1 ) ) – 1 )
2.51 = 3.141 /2 * ( SQRT ( y + 1 ) / ( y – 1 ) ) – 1 )
y = 1.50.
