    Pipe Velocity
AI Thread Summary
The discussion focuses on calculating the velocity of air flowing through a 6mm diameter pipe at a pressure of 3 bar. The formula provided for determining outlet velocity is v_out = [2(p_in - p_out)/air_density + (v_in)^2]^0.5. There is uncertainty regarding the inlet velocity, which is crucial for accurate calculations, and the impact of pipe radius on flow speed is noted, with faster movement at the center compared to the circumference. The conversation touches on gas dynamics, suggesting that the outlet velocity may approach Mach 1 under certain conditions. Accurate calculations depend on knowing both inlet velocity and air density.

Can someone help me here i need to find the velocity through straight pipe with length 0.11meter and diameter 6mm and air flows through the pipe at a pressure of 3bar. Now i want to find the velocity of air through the outlet in m/s?

if I understand your question right

v_out = [2(p_in - p_out)/airdensitiy + (v_in)^2]^0.5

iam using a pressure of 3bar in compressor i don't know what is the velocity at inlet.
 
Velocity at what radius? The air at the center of the pipe will be moving faster than the air at the circumference.
 
sounds like a gasdynamics. 3 bar in a compresser? Mach 1 at outlet.
 
Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...
Is it possible to arrange six pencils such that each one touches the other five? If so, how? This is an adaption of a Martin Gardner puzzle only I changed it from cigarettes to pencils and left out the clues because PF folks don’t need clues. From the book “My Best Mathematical and Logic Puzzles”. Dover, 1994.
