- A 0.485-m-long brass pipe open at both ends has a fundamental frequency of 347 Hz. (The coefficient of linear expansion for brass is 19 ✕ 10−6 °C−1.) a) Determine the temperature of the air in the pipe. b) If the temperature is increased by 22.0°C, what is the new fundamental frequency of the pipe? Be sure to include the effects of temperature on both the speed of sound in air and the length of the pipe.An organ pipe that is open at both ends has a fundamental frequency of 348 Hz at 0.0°C. What is the fundamental frequency for this pipe at 30.3°C?A long tube contains air pressure of 1 atm. and temp of 77degrees C. the tube is open at one end, and closed by a movable piston on the other end. A tunning fork is near the open end and is vibrating at a frequency of 500Hz. Reasonance is produced when the piston is set at 18, 55.5, and 93 cm. From these measurements what is the velocity of sound in air at 77degC. I'm getting 375m/s and I don't think it is right because I was a little confused on my process. I appreciate your help with this problem. Thank you.
